Bump --text-faint from #746a58 (4.01:1 on cream surfaces — fails AA)
to #665c4b (4.94:1 — passes AA for small text). Preserves the "quieter
than --text-dim" semantic the variable was named for. Lifts ~33 sites
into compliance with one diff.
Also keeps the BoardPostCard per-selector swap to --text-dim that
shipped with the original /board fix; can revert to --text-faint
in a follow-up now that the variable itself is accessible.
Delete uses findOneAndDelete with author match (no TOCTOU window);
existence check only runs on miss to distinguish 403 vs 404. Posts
list capped at 200. Drop unused resolveTagChannel and refreshParams;
route slack URL building through the composable's slackUrl helper.
Replace window.confirm with an inline Delete? / Cancel / Confirm flow on
post cards. Add focus-visible outlines, initials in avatar placeholders,
and promote post/form titles from h3 to h2 for heading order.
