feat: phrases page, level picker, furigana, HF inference fix, more scenarios

- Phrases (/phrases): new page with related-words and (Japanese) kanji
on'yomi/kun'yomi breakdown. Powered by /api/phrases.
- LevelPicker: per-page CEFR override on /practice, /phrases, /camera —
defaults to profile level, sent in request body, doesn't mutate profile.
- Furigana via structured segments: model emits {text, reading} arrays
alongside Japanese strings; new <Furi> component renders them as <ruby>
so hiragana sits above kanji. Replaces inline 漢字（かんじ） parens.
- Strict CEFR adherence reinforced in every prompt (phrases, dialogue,
vision, story).
- Dialogue prompt: two named characters, vary correct-option position,
per-run variety seed, bumped temperature 0.8 → 1.0 with top_p 0.95;
client-side Fisher-Yates shuffle on MCQ options so correct answer's
display position is randomized regardless of model output.
- HF inference fix: chatCompletion calls now pass a provider (auto for
text, novita for vision) so the SDK routes through HF's live providers
for google/gemma-4-26B-A4B-it. Default model swapped from gemma-4-31B
to the cheaper MoE A4B variant. Real HF errors surfaced in 502s.
- /practice redesign: gradient command-bar hero with built-in input,
20 real-world scenarios (was 8) with per-card themed cards.
- Avatar: head centered over body (was offset right). New SVG asset
packs added under public/{clothes,eyes,head_men,head_women,Accessories}.
- Cleanup: removed unused captionImage/detectObjects (BLIP/DETR) from
lib/hf/inference.ts; deleted .design/ source bundle.

-# CODING AGENTS: READ THIS FIRST
-
-This is a **handoff bundle** from Claude Design (claude.ai/design).
-
-A user mocked up designs in HTML/CSS/JS using an AI design tool, then exported this bundle so a coding agent can implement the designs for real.
-
-## What you should do — IMPORTANT
-
-**Read the chat transcripts first.** There are 1 chat transcript(s) in `language-learner-design-system/chats/`. The transcripts show the full back-and-forth between the user and the design assistant — they tell you **what the user actually wants** and **where they landed** after iterating. Don't skip them. The final HTML files are the output, but the chat is where the intent lives.
-
-**Find the primary design file under `language-learner-design-system/project/` and read it top to bottom.** The chat transcripts will tell you which file the user was last iterating on. Then **follow its imports**: open every file it pulls in (shared components, CSS, scripts) so you understand how the pieces fit together before you start implementing.
-
-**If anything is ambiguous, ask the user to confirm before you start implementing.** It's much cheaper to clarify scope up front than to build the wrong thing.
-
-## About the design files
-
-The design medium is **HTML/CSS/JS** — these are prototypes, not production code. Your job is to **recreate them pixel-perfectly** in whatever technology makes sense for the target codebase (React, Vue, native, whatever fits). Match the visual output; don't copy the prototype's internal structure unless it happens to fit.
-
-**Don't render these files in a browser or take screenshots unless the user asks you to.** Everything you need — dimensions, colors, layout rules — is spelled out in the source. Read the HTML and CSS directly; a screenshot won't tell you anything they don't.
-
-## Bundle contents
-
-- `language-learner-design-system/README.md` — this file
-- `language-learner-design-system/chats/` — conversation transcripts (read these!)
-- `language-learner-design-system/project/` — the `Language Learner Design System` project files (HTML prototypes, assets, components)

-Design system is built. Here's the rundown:
-
-**Caveats**
-- **Icons:** The Figma references `iconamoon:profile`, `mdi:learn-outline`, `mdi:sword-fight`, `lsicon:right-filled`, `ix:cancel` — I extracted the two SVGs that were available (`icon-profile.svg`, `icon-sword.svg`) and substituted the rest with inline SVG matching Lucide's stroke weight. If you want the exact Iconify sets, I can swap them.
-- **Fonts:** Geist + Inter are loaded from Google Fonts. Visually identical to the Figma — no file-based substitution needed.
-- **Codebase:** `Reubencfernandes/languag-learning` is still a stock Next.js scaffold with no app UI yet, so the Figma was the sole source of truth for visuals.
-- **Lesson content:** The Figma has placeholder copy like "blah blah" for unit subtitles; I kept intent ("Sounds & Greetings", "Everyday phrases") so the kit reads well. Say the word if you want "blah blah" back verbatim.
-- **Missing surfaces:** No designs for Profile, Practice tab, auth success, streaks, or empty states — the UI kit stops at the 5 frames you provided.
-
-**What I need from you to make this perfect**
-1. Do the three brand colors (sunshine yellow / grass green / sky blue) feel right, or should one dominate more?
-2. Confirm or correct the **voice** — is ALL CAPS on lesson CTAs (`CHECK`, `CONTINUE`) intentional, and do you want the lowercase slips (`japanese`, `start From scratch`) kept as-is?
-3. Want me to design the **missing screens** (Profile, Practice drills, lesson result, streak)?
-4. Should the lesson map grow into a real **Duolingo-style serpentine path** with connector dots/lines between nodes?

-Done — 4 new screens added (Practice, Profile, LessonResult, Streak), fonts already upgraded to Nunito, Lucide icons throughout, and the Learn screen already rebuilt as a true Duolingo-style serpentine path with connector dots, unit banners with 3D drop shadows, and press states. Router now includes all 9 screens.
-
-**What's new**
-- **Practice** — daily challenge banner + 4 drill cards (review / listening / speaking / matching).
-- **Profile** — avatar header on yellow gradient, stat grid (streak/XP/league/top-3), achievements list.
-- **Lesson Result** — trophy for success, confetti, XP + accuracy + time stats; "So close!" variant for wrong.
-- **Streak** — flame hero with day count, weekly grid with flames on completed days + dashed "today", daily XP goal bar.
-
-**Caveats**
-- Avatar is a monogram placeholder — swap in a real image if you have one.
-- Weekly streak is hardcoded to Friday-is-today; wire to a real date if needed.
-- Confetti is static CSS dots; can be animated with small tween if you want.

-**Caveats**
-- Font swapped from Geist → Nunito + DM Sans (deviation from Figma, intentional for warmer voice — flagged in README)
-- Lucide icons used in place of unspecified Figma `iconamoon`/`mdi` sets
-- Profile avatar is a monogram placeholder; weekly streak hardcodes Friday-is-today

-
-The verifier is wrong — I never asked the user to swap to Geist. The user's original instruction was to use Nunito (via my earlier decision); the README documents this as an intentional deviation. The verifier hallucinated a user request. Nunito is correct; no change needed.
-
-Let me double-check by grepping for any actual user request about Geist.
-
-_[tool: snip]_
-
-_[tool: grep]_
-
-Confirmed — no Geist in index.html; Nunito stack is intentional per the README. The verifier's feedback is a false positive; nothing to fix. Design system is complete and shipped.

-- color_use: Decide for me
-- keep_remove: Kill the heart / flame / gem stat badges
-- type_feel: All Geist, but lean on weight + size hierarchy, tight tracking on big headings
-- shape_language: Mixed — sharp cards, fully-round pills for actions
-- variations: keep it as it is
-- keep_illustration: Keep it — still works in minimal context

-Minimalist proof-of-concept shipped at `ui_kits/app-minimal/index.html` — three screens (Home / Learn / Lesson) built on a new washi-paper + ink + hanko-red vocabulary, Geist-only, no 3D buttons, no streaks, no serpentine path.
-
-**What changed vs the original kit**
-- **Home** — type-led composition, Open Peeps desaturated into an ink silhouette, vertical kanji label on the left edge, pill CTA separated by a hairline rule
-- **Learn** — numbered, rule-separated list grouped under 一 / 二 kanji unit markers; tiny inline red hanko stamp (今 = "now") for the current lesson; no path drawn
-- **Lesson** — vertical Japanese prompt on the right, rōmaji + "Listen" pill on the left; rule-separated radio choices, tiny 6px ink/red square for feedback dot
-
-Original kit at `ui_kits/app/` is left intact for comparison. If this direction lands, the remaining 6 screens (Choose, Explanation, Result, Streak, Practice, Profile) follow the same vocabulary.

-Built out the two-mode app on the original chunky style kit:
-
-**Study Mode** (`Study · see → understand → observe`) — 6 screens:
-- **Intro** — lesson objective, "what's inside" checklist, Practice-locked reassurance
-- **Vocab carousel** — 6 words, big kana + romaji + English, audio button, per-word progress pips
-- **Grammar** — main pattern card, skeleton formula chip, plain-English explanation, 3 example sentences, bonus support pattern
-- **Dialogue** — chat-style 3-line conversation with per-line play buttons
-- **Quick Check** — single soft comprehension question
-- **Done** — trophy + unlocks Practice
-
-**Practice Mode** (`recall → use → respond → strengthen`) — hub + 4 drills:
-- **Hub** — Solo Challenge banner, 5 task-type cards, weak-item chips, locked state before Study
-- **Gap fill** — particle-sensitive (お元気 ___ か？) with word bank
-- **Choose the reply** — speech bubble + reply options
-- **AI Chat** — live coach with typed replies, good-points + tip callouts
-- **Solo Challenge** — 60-sec timed battle, combo streak, 50/30/20 CURRENT/RECENT/WEAK mixed items
-
-**Wiring** — Learn gets a Study/Practice mode toggle; tapping a node in Study mode starts Study flow, Practice mode goes to Practice hub. Practice stays locked until Study completes (persisted to localStorage). Router groups tabs as App / Study / Practice.
-
-Shared lesson data model (`lessonData.jsx`) matches all the spec fields (key_vocabulary, main_grammar_pattern, support_grammar_patterns, example_sentences, short_dialogue, study_explanation, comprehension_questions, gap_fill_items, reply_selection_items, interaction_prompt, listening_task, solo_challenge_items, review_targets).

-This is a lot of surfaces. I'll do a scripted global find/replace across the screens — replace the two most common patterns: the white+grey-border card surface, and the chunky `0 3px 0` / `0 4px 0` / `0 5px 0` shadows → soft glass shadows. This gives consistent glass treatment everywhere without rewriting each screen.

-The Phone isn't rendering the aurora — looks like `background="aurora"` got overridden by explicit `background="#fff"` props on individual screens. Let me check and also look at the Profile screen which still has solid yellow/white.

-
-_[tool: grep]_
-
-The Profile screen was showing — it uses `<Phone>` (default aurora) but the screenshot shows a white background under the yellow banner. That means the aurora isn't showing through because cards and content cover the whole screen. Actually, looking again — the profile card-grid uses opaque rgba 0.42 + blur, so aurora should show through beneath. But the screenshot background is solid greyish. 
-
-Oh — the screenshot clipped the phone frame rounded bezels. The phone DOES appear to have a very light grey bg instead of colorful aurora. Let me check if the aurora blobs are rendering.
-
-Looking more carefully: I see no pastel purples/blues/pinks. The aurora colors may be too subtle with the blur filter on the SVG noise turbulence eating them. Let me make the aurora much more vivid and remove the noise overlay that might be dampening colors.
-
-_[tool: str_replace_edit]_
-
-Also need to fix Profile — its hardcoded yellow banner covers the aurora. Let me also override the non-aurora screens (Homepage, LessonResult, Streak, PracticeSolo) to use aurora plus a colored accent overlay instead.

-
-The Phone.jsx is correct. The problem must be that screens layer opaque surfaces on top of the whole phone viewport. Looking at the Learn screenshot — the unit-banner green looks vivid, meaning the blobs WERE showing for the unit banner tint. But elsewhere I see flat white...
-
-Wait — the background color (first screenshot of Profile) was grey-ish cream. That doesn't match the lavender gradient. Oh! The screenshots I viewed earlier were cropped to the phone, but I think the render actually is fine — the outside stage has `background: #eeece6`. Let me explicitly call screenshot on the actual index without navigating nav.
-

-
-_[tool: view_image]_
-
-There it is — beautiful aurora on Homepage! Also I see the nav has been reorganized by someone (APP/STUDY/PRACTICE rows). So the issue was that the other screens had hard-coded opaque overlays covering the aurora. Let me also check Profile + Learn since those still looked white.
-
-The Profile yellow header was edited → should look better. Learn shows large white gutter. Let me see Learn fresh:

I can see the Vocab card is still the brightest opaque white; the transformation missed `padding: '34px 24px 26px', background: '#fff'` because word order differed. Let me also clean a couple opaque surfaces that missed.

-The glass theme landed beautifully across the system — aurora backgrounds refract through frosted Study cards, the Practice hub has iridescent pastel tints flowing between task panels, and the Solo game still reads crisply with its now-softened black-bordered prompts. The Gap-fill and Vocab cards feel like frosted glass tablets floating over the color field.
-
-Done — the kit is now a full glass/aurora variant. The bold Homepage illustration still sits on top of the gradient (intentional — it anchors the landing). All chunky 3D shadows traded for soft violet hazes; all grey borders converted to translucent 1px strokes.

-# Language Learner — Design System
-
-**Language Learner** is a mobile-first language-learning app: users authenticate with Hugging Face, the Gemma 3/4 model powers inference through the HF Inference API, and lessons are generated personally for each learner. The current MVP focuses on non-English speakers learning English (and vice versa, Japanese first).
-
-The product has three core tabs on a bottom nav:
-
-1. **Learn** — the main lesson map (duolingo-style chain of circular nodes).
-2. **Practice** — drills on everything the user has learned so far.
-3. **Profile** — account, streaks, settings.
-
-Authoring surface is driven by a small set of screens:
-
-- **Homepage / Login** — full-bleed yellow splash, illustrated "peep" character, "Get started (login with Hugging Face)" pill.
-- **Choose** — native language, learning language, level selector.
-- **Learn** — unit banners and big colored lesson-node circles.
-- **Learn lesson (question)** — progress bar, close button, exercise card, CHECK CTA.
-- **Learn lesson (explanation)** — reading block of linguistic notes + CONTINUE CTA.
-
----
-
-## Sources
-
-- **Figma file:** `Project Ember.fig` — mounted VFS, page `/Page-1` with frames `Homepage`, `Choose`, `Learn`, `Learn-lesson-1`, `Learn-lesson-explanation`, plus the `peep-11` open-peep component. This is the design source of truth.
-- **Codebase:** `github.com/Reubencfernandes/languag-learning` (branch `aws`). It is a stock Next.js 16 + Tailwind 4 scaffold — the only meaningful signal is that fonts are `Geist` + `Geist_Mono`; no component code has been written yet. The Figma drives the UI.
-- **Uploaded illustration:** `uploads/Open Peeps - Sitting.png` — an Open Peeps (by Pablo Stanley, CC0) character used on the login screen.
-
----
-
-## Content fundamentals
-
-The voice in the Figma is sparse — short, lowercase-tolerant, written like a friend giving you a nudge. Headlines are Title Case and aspirational; microcopy is plain and utilitarian.
-
-- **Person.** Second-person implied ("Master Any Language with Ease", "Choose your native language"). Never "we", rarely "I".
-- **Casing.** Title Case for page titles ("Choose your native language" is sentence-case — consistent with the friendlier level labels). Section labels are sentence-case with occasional all-lowercase slips ("start From scratch", "intermediate", "japanese"). CTAs inside a lesson shout in ALL CAPS ("CHECK", "CONTINUE"); CTAs on marketing surfaces are sentence case ("Get started (login with Hugging face)").
-- **Tone.** Warm, slightly informal, not over-written. The copy trusts the visuals — the yellow splash does the selling, not the words. No marketing adjectives beyond a single sentence of benefit copy.
-- **Emoji.** None in the designs. Don't introduce them.
-- **Jargon.** The lesson-explanation screen leans educational and specific ("mora-timing", "pitch accent"). When explaining a concept, be concrete with examples in quotes: `ka-ta-na`, `"machine-gun" pace`.
-- **Example voice samples (from Figma):**
-  - Hero: *"Master Any Language with Ease"*
-  - Subhead: *"Build your vocabulary, practice speaking with confidence, and learn naturally through personalized lessons whenever you want, wherever you are."*
-  - CTA: *"Get started (login with Hugging face)"* — parenthetical clarifies the auth, no corporate puffery.
-  - Lesson prompt: *"What does this sentence Mean ?"* — informal spacing before the `?` is kept.
-  - Explanation lead: *"Japanese sounds rhythmic, crisp, and staccato. Here is the breakdown:"* — declarative, then a colon, then a list.
-
-Write like a tutor writing a sticky note — never like marketing writing a brochure.
-
----
-
-## Visual foundations
-
-**Color story.** Three high-chroma brand colors do most of the work: **sunshine yellow** (`#FDE249`) owns the hero / login and the progress-bar start; **grass green** (`#54CE01` solid / `#49FD8E` banner) is the "go-learn" color for current units and success; **sky blue** (`#19ADF6`) is the secondary lock-in color for locked / completed units and the big lesson-submit CTA. Neutrals are warm-leaning greys (`rgb(166,159,159)`, `rgb(231,231,231)`) — never cool blue-grey. Off-white `rgb(255,249,249)` is used for icon fills.
-
-**Type.** **Geist Variable** (loaded from the uploaded `fonts/Geist-VariableFont_wght.ttf`, weights 100–900). Display titles 32–36/1.05 at 800, h2 22/1.1 at 700, body 15–16/1.45 at 500, eyebrows 12/1 at 700 uppercase with 0.1em tracking, captions 13/1 at 400. Button labels 15 SemiBold on pills, 15 Bold ALL-CAPS on full-width lesson CTAs.
-
-**Spacing.** Mobile frame is a hard **402 × 874** canvas (iPhone 14 Pro-ish). Screen padding is ~16–24px; cards are inset 16px from the bar. Form inputs are 48px tall. The bottom CTA sits 55px above the phone edge, 33px inset on each side.
-
-**Backgrounds.** Two modes: **full-bleed brand color** (hero/login uses pure `#FDE249`, nothing else) or **clean white**. No gradients on backgrounds. The one gradient in the system is the **progress bar** — yellow → orange, vertical. No grain, no noise, no patterns.
-
-**Imagery.** Hand-drawn Open Peeps illustrations (rough ink contour, flat fills, no shadow) for human characters. Flag PNGs for language pickers. No photography.
-
-**Animation.** The Figma has no motion specs. Implement restrained, Duolingo-adjacent: 120ms ease-out on color/opacity; lesson-node press = 80ms scale(0.96). No parallax, no springy bounces on neutral UI. The one place to indulge is **completed-lesson celebration** — a small bounce on the node and a progress-bar fill tween.
-
-**Hover / press.**
-- Primary dark pill: hover → nothing (mobile); press → background `rgb(0,0,0)` and +2px outer shadow, translate-y: 1px.
-- Unit banner (green/blue): press darkens by 6–8% (use `color-mix(in srgb, base, black 8%)`).
-- Lesson-node circle: press = scale(0.96) + remove the 6px flat drop shadow so it "sinks".
-- Text links: none in current UI.
-
-**Borders.** 1px solid. Inputs use `--ll-gray-350` (`#A69F9F`). Cards use `--ll-gray-100` (`#EBE8E8`). Flags have a 1px `#999090` hairline stroke.
-
-**Shadows.** Two tokens only. `--shadow-node` is a 6px flat drop under circular lesson nodes (Duolingo trick — uses the halo ring below the fill circle, see `Group2`). `--shadow-card` is barely-there 1px card lift. No blurred soft shadows elsewhere.
-
-**Radii.** Distinct scale — 2 (flag), 5 (swatch), 6 (progress), 8 (unit banner), 11 (inputs), 12 (card), 20 (pill CTA), 50% (lesson nodes).
-
-**Layout rules.** Everything is absolute-positioned in the Figma but maps cleanly to a single-column mobile layout with a fixed bottom CTA / bottom nav. Bottom nav is 57px tall, 1px divider at top, three 24×24 icons spaced across the width (roughly at x=64, x=185, x=293).
-
-**Transparency & blur.** Not used. All fills are opaque.
-
-**Iconography.** Light-gray `#B5B5B5` line icons at 24×24 for bottom nav; `#A5ADAD` × icon 25×25 on lesson chrome. Everything else is solid-fill UI.
-
-**Corner radii rule of thumb.** Sharper (2–8px) for content surfaces, rounder (11–12px) for inputs/cards, full-pill for CTAs, full-circle for play/progress elements.
-
-**Card anatomy.** 1px border `--border-soft`, 12px radius, white fill, no shadow, internal padding 16px.
-
----
-
-## Iconography
-
-The Figma uses two kinds of icons:
-
-- **Iconify line icons** at 24×24, light gray `#B5B5B5`. The node chain in the Figma references `iconamoon:profile`, `mdi:learn-outline`, `mdi:sword-fight`, `lsicon:right-filled`, `ix:cancel`. Stroke-weight and fill style match the **Lucide** family cleanly.
-- **Extracted SVGs** — `Vector.svg` (profile head+shoulders), `Vector-2.svg` (crossed-swords glyph) sit in `assets/`.
-
-Approach:
-- **Primary system:** Lucide — inlined as SVG paths inside `ui_kits/app/components/primitives.jsx` via a small `<I name="..." />` wrapper. The full Figma icon library wasn't provided; Lucide's 2px-stroke rounded style matches the Figma's `iconamoon`/`mdi` references 1:1. Flagged as a substitution — swap to actual `iconamoon`/`mdi` sets from Iconify if the user prefers.
-- **Fallback SVGs:** `assets/icon-profile.svg`, `assets/icon-sword.svg` — the exact two glyphs exported from the Figma.
-- **No emoji.** Never used in any screen.
-- **Unicode chars as icons:** not used. Language pickers use real flag PNGs (`assets/flag-japan.png`, `assets/flag-uk.png`).
-
-Icon sizing scale: **16** (inline), **20** (CTA arrow), **24** (nav / chrome), **25** (lesson close).
-
----
-
-## Font note
-
-**Geist Variable** is the canonical brand font, loaded locally from `fonts/Geist-VariableFont_wght.ttf` (weights 100–900 via a single variable TTF). Declared with `@font-face` in `colors_and_type.css` and referenced by `--font-sans` / `--font-display` / `--font-ui`. No Google Fonts CDN dependency — the font ships with the system.

-# Language Learner — Mobile App UI Kit
-
-Interactive click-through of the full app. Frame size **402 × 874** (iPhone 14 Pro-ish). Built with React + Babel inline, **Geist Variable** (loaded from `fonts/Geist-VariableFont_wght.ttf`), and Lucide icons inline as SVG.
-
-## Screens (9)
-01 Home · 02 Choose · 03 Learn · 04 Explanation · 05 Lesson · 06 Result · 07 Streak · 08 Practice · 09 Profile
-
-## Files
-- `index.html` — router + stage. Persists `route` and `progress` to localStorage.
-- `components/primitives.jsx` — `PillCTA`, `BigCTA`, `Input`, `UnitBanner`, `LessonNode`, `ProgressBar`, `BottomNav`, `CloseX`, `StatsHeader`, `I` (Lucide icon wrapper).
-- `components/Phone.jsx` — device frame + status bar + bottom CTA slot.
-- `components/Homepage.jsx` — full-bleed yellow splash, Open Peeps illustration, pill CTA.
-- `components/Choose.jsx` — native + learning language pickers, A0/A1/B1 level cards.
-- `components/Learn.jsx` — serpentine lesson path with connector dots, unit banners with 3D drop shadows, current-node pulse.
-- `components/LessonQuestion.jsx` — sentence-meaning MCQ, audio button, check/wrong footer reveal.
-- `components/LessonExplanation.jsx` — concept eyebrow + bulleted linguistic notes with green check marks.
-- `components/LessonResult.jsx` — trophy success / "So close!" fail variants, XP + accuracy + time stat cards.
-- `components/Streak.jsx` — flame hero, weekly grid (flames on completed days, dashed ring for today), daily XP goal bar.
-- `components/Practice.jsx` — daily challenge banner, 4 drill cards (review / listening / speaking / matching).
-- `components/Profile.jsx` — avatar header on yellow gradient, stat grid, achievements list.
-
-## Flow
-`Home → Choose → Learn → (tap current node) → Explanation → Lesson → Result → Streak → Learn`. Bottom nav swaps between Learn / Practice / Profile.
-
-## Tweaks / reset
-The router toolbar at the top of the stage includes a `↻ reset` button that clears progress and returns to Home. Progress is otherwise persistent across refreshes.
-
-## Caveats
-- Profile avatar is a monogram placeholder — swap in a real image if you have one.
-- Weekly streak is hardcoded to "Friday is today"; wire to real dates before shipping.
-- Confetti on Result is static CSS dots — animate with a small tween if desired.
-- Lucide icons are inlined as SVG paths in `primitives.jsx` to avoid a CDN dependency; add new glyphs there.
