"""TEXT module for openScale (a body-weight / health tracker).

CONTENT / OUTPUT text — this lane is the sole owner of exact-string equality.
Every EXPECTED string below was OBSERVED on the RUNNING ORIGINAL (recon + live
dumps), never read from the source tree, and never a version/build/copyright value
(a recreation cannot know those).

WHAT THIS LANE ASSERTS (all rule assertions unless suffixed _vlm):
  * empty-state strings that an interaction/state PRODUCES:
      - "No User Active"           (fresh launch, no user)
      - "No Measurements Yet"      (user exists, no measurement) — ABSENT before the
                                    user is created, PRESENT after (the change)
  * TopBar screen titles reached through the drawer: Overview / Charts / Table /
    Statistics / Insights / Settings — each ABSENT on the Overview source surface,
    PRESENT after navigating (the discriminating change).
  * Settings sub-screen titles: General / Chart / Measurement Types / About.
  * the 5 exact Insights placeholder card strings (bodies).
  * Statistics per-metric Min/Max/Avg labels+values, produced by saving a
    measurement: "Min: 80 kg", "Max: 80 kg", "Avg: 80 kg", "Min: 24.7",
    "Min: 1840 kcal", "Min: 2208 kcal".  (The NUMBER is computation's; here we own
    the exact rendered STRING incl. the "Min:/Max:/Avg:" label and unit.)
  * Overview measurement-card value strings: "80 kg", "24.7", and the "Show more"
    expand affordance — each ABSENT before a measurement exists, PRESENT after.

OPAQUE TEXT CORES -> the 3 _vlm (canvas-baked axis text, absent from the view tree):
  * Overview chart: the "6 Aug" date label baked onto the plot canvas.
  * Charts screen TOP chart: the horizontal date axis ("Aug" day labels).
  * Charts screen LOWER chart: the "80" weight y-axis label.

DEVICE QUIRKS honored (from recon):
  * BACK discards an in-progress form -> fill Name+Height then tap the top-right
    Save button DIRECTLY; never hide_keyboard() before saving.
  * NumberInputDialog EditText APPENDS to "0.0" -> tap "Clear" first; and
    type_text drops the 2nd digit -> enter multi-digit values ONE char at a time
    and VERIFY the field before proceeding.
  * Each test owns its entry via restart_app()/clear_data(); state persists within
    a run but no test depends on another.
  * ui() is re-dumped after every change (kit invalidates coordinates on change).
  * depth>=1 is backed by file-local and_enter_*/and_reach_* helpers.
