Session H (night2): design pass — §2 locks + honest waiting sweep

- QA.20: one meaning per color, locked — STEAM amber (caution), VALUE
  green (edge), red only at STALE/miss; revisions render the original
  grade struck through on slate AND ledger.
- QA.21: every new data surface (PriorReads, PlayerStreaks, ModelRecord)
  renders data in mono (tabular-nums via the .mono class).
- QA.22: waiting copy derives from the real cron schedule on every
  surface (StatStrip, dashboard, Explore) — no passive mystery anywhere.
- Explore empty state joined the honest-waiting lib.
- Sweep result: no raw brand hexes and no sans-serif data in tonight's
  components (sans only on prose/captions/hero letter — sanctioned);
  glow confined to A-tier badges + reveal chrome; 390px containment
  holds (wrapping chips, scroll-contained tables from Phase 3 rules).

Backend 2352 -> 2396 tests (205 suites), web build exit 0.
