/* ==========================================================================
   Sophicly Drill v3.57.0 — Final-Read Pass · Tense Lock · Purpose Sharpener
   Ported from the prototype Neil approved (2026-10-10). Borderless: surfaces
   separate by elevation and tint, never a stroke (BRAND §127.2). Teal for
   "you are here"; green / amber / red only for first try / second / missed.
   Purple is attainment, so it is not used here.
