PICK SKY DEL: server purge of seat Character + race guards stop the btn from re-injecting; readonly opacity bump (0.6 → 0.85) — TDD

Two related Sky Select bugs the old DEL flow couldn't address. (1) DEL btn lingered after a clear because an in-flight schedulePreview's .then() could resolve AFTER the OK callback ran, calling _ensureDelBtn() against a freshly-cleared wheel-col. (2) Sky data rehydrated on refresh because clicking SAVE SKY confirms a Character row on the seat — the DEL handler only purged localStorage & in-memory state, leaving the durable Character row to drive subsequent renders.

Server: new epic.sky_delete(room_id) view (POST → JsonResponse {deleted:True}) deletes every Character on the requesting gamer's seat where retired_at is null — drafts (confirmed_at NULL) and confirmed rows alike. 405 on GET, 403 for outsiders, never touches User.sky_chart_data (Dashsky/My Sky applet's DEL owns that side).

JS (_sky_overlay.html): DEL OK callback now (a) bumps a _fetchSeq counter so any in-flight schedulePreview .then()/.catch() short-circuits when its captured seq != current — kills the re-injection race; (b) clearTimeout-s _chartDebounce + _placeDebounce so a typed-just-before-DEL keystroke can't fire schedulePreview after the clear; (c) POSTs to DELETE_URL (overlay.dataset.deleteUrl wired via {% url 'epic:sky_delete' room.id %}) so the seat's Character row is dropped server-side; (d) clears LS + DOM state as before.

SCSS: .sky-field input[readonly] opacity 0.6 → 0.85, & dropped the redundant .sky-coords > div input { opacity:0.6 } that was previously winning the cascade by virtue of being declared later. The browser's default ::placeholder is ~0.54, so 0.85 × 0.54 ≈ 0.46 — close to the birth-place placeholder's ~0.54 effective opacity per the user's "appreciably higher tho not opacity 1" target. Values land at 0.85 (clearly readable but still de-emphasized vs. the editable place input).

Tests: 4 new ITs in PickSkyRenderingTest cover (a) POST clears confirmed Character, returns JSON {deleted:True}; (b) 405 on GET; (c) 403 for non-seat-owner; (d) User.sky_chart_data untouched by in-room DEL. PickSkyDelTest FT picks up an extra assertion: id_sky_delete_btn must be absent from DOM after OK (the bug-1 regression guard). 55-test sky suite green.
