A.7.5-polish-3 stat-block alpha unification (1.0) — supersedes polish-2's 0.5. User-reverted 2026-05-25 PM: "please undo that and set all of them to the higher opacity that My Sign just had". The 0.5 unification from polish-2 (efcef15) made all 4 stat-blocks too washed-out against the page bg bleed; user wants them fully opaque matching the My Sign applet's original gravity-state appearance (= rgba(var(--priUser), 1)). Forward edit rather than git revert since the polarity-bg + label-color collapses from earlier polish commits stay in place — only the alpha changes.

**5 sites bumped from 0.5 → 1.0** (mirrors the polish-2 site list):
- `.sig-stat-block` default (the my_sign main + sig-overlay reference)
- `.sea-stage-content .sea-stat-block` (no-polarity fallback)
- `.sea-stage--gravity .sea-stat-block, .sea-stage--levity .sea-stat-block` (polarity-classed rule that actually applies in practice)
- `.tarot-fan-wrap[data-polarity="gravity"] .fan-stage-block, .tarot-fan-wrap[data-polarity="levity"] .fan-stage-block`
- `.my-sign-applet-stat-block` default

Net: every stat-block surface now renders `rgba(50, 30, 95)` (--priUser at full alpha) regardless of polarity. Visually identical chrome across my_sign main / applet / sea_stage modal / Game Kit fan stage — no more translucent leak of the page bg through the panel.

Tests: 1314/1314 IT+UT total green (74s; pure alpha-channel SCSS, no test surface). Visual verify 2026-05-25 PM: applet stat-block now `rgb(50, 30, 95)` (full opacity), matching its original gravity state the user references as canonical.
