Revert universal .btn-disabled → × pseudo-element overlay (iter-4c); restore case-by-case × rendering convention. My Sea DEL btn now swaps DEL ↔ × in lockstep w. its .btn-disabled toggle (matches game-kit tooltip + DON/DOFF pattern). User-spec 2026-05-20.

The iter-4c bundle added a universal `&::before { content: "\00d7"; ... }`
overlay on every `.btn-disabled` button + hid native text via
`> * { visibility: hidden }` + `color: transparent`. Visually flattened
every disabled state across the app (DEL, FLIP, DON/DOFF, palette
swatches, etc.) onto a single × glyph — user-rejected: "ruined the old
UX appearance".

Revert restores `_button-pad.scss` to its pre-iter-4c shape:
`color: rgba(--secUser, 0.25)` dims native text in place; no overlay,
no inner-content hiding. Templates that want a × on disabled buttons
render it explicitly in their own markup (game-kit tooltip `<button
class="btn-equip btn-disabled">×</button>`, my_notes DON/DOFF, etc.).

My Sea DEL btn picks up the case-by-case convention: template renders
`{% if hand_complete %}DEL{% else %}&times;{% endif %}`; the picker's
`_setComplete(on)` JS handler swaps `delBtn.innerHTML` between `DEL`
and `×` in lockstep w. the `.btn-disabled` class toggle so visual +
label always agree post-hand-completion.

FT `test_form_col_renders_decks_lock_hand_del_and_reversal_pct` now
asserts `delbtn.text == "×"` instead of relying on the (now-removed)
pseudo-element comment.
