my-sea deck-stack + spread-card glow: unify hover-reveal / click-persist + --ninUser halo — TDD

Unify the glow/FLIP interaction across the owner picker (my_sea) + the read-only
spectator (my_sea_visit), then carry the same selection halo onto the spread
cards + deck-stack faces.

DECK STACK (user-spec 2026-05-30) — the owner revealed the FLIP only on click
(persisted) but never on hover; the spectator revealed it on hover but never
persisted. Now BOTH do both:
- `.sea-stack-ok` reveal is a single shared rule in _card-deck.scss — opacity
  fades in on hover/focus (ephemeral) OR via the JS-set `.sea-deck-stack--active`
  class (click-persist, same class the face-glow rides). The owner's inline
  `display` toggling is gone (`_showOk`/`_hideOk` just flip `--active`); the
  spectator's hover-only override in _gameboard.scss is removed.
- Interactivity stays gated on `--active`, NOT hover: hover is a purely VISUAL
  preview (matching the spectator's disabled FLIP). This preserves the owner's
  two-step deal — were the FLIP click-through on hover, a single stack-click
  would land on the centred FLIP + deal early (caught by the draw FT).
- Spectator persist wired in my_sea_visit.html (click a stack → `--active`,
  click elsewhere clears); its FLIP stays `.btn-disabled` (read-only).

SPREAD CARDS — the same hover-glow + active-persist now on EVERY spread card,
building on the cover/cross rules. The prior `.sea-card-slot--focused` glow
(0-1-0) was silently overridden by the filled-card drop-shadow ladder (up to
0-4-0) and never rendered (verified live); `!important` (consistent w. the
existing `opacity:1 !important` there) makes the halo win on hover + focus. The
halo is symmetric (rotation-invariant). No colour change — box-shadow only.

DECK FACE HALO — the levity + gravity stack glows now mirror the card halo's
tuned geometry (0.5rem blur / 0.5rem spread / 0.3 alpha), each in its own
polarity colour (--ninUser / --quaUser); single keeps its own tone.

Verified live in Firefox: deck FLIP persists on click + fades on hover; the card
halo wins over the drop-shadow on hover/focus across crown/cover/(reversed-)cross;
levity/gravity deck glows match the card halo. Draw FTs green (single-draw, hand-
completion, AUTO DRAW, auto-drawn-slot reopen) — the two-step deal + card focus
survive the display→opacity switch.
