/* hm-board-fixes.css — 2026-05-27 post-rollback patches
 *
 * 1. mbskin (login/register/password recovery) — give the bare gnuboard
 *    core form a readable layout: centered, padded, max-width-bounded.
 * 2. board list header (.hm-list-header) explicit hide rules per board
 *    style so variant CSS grid does not re-show it.
 * 3. Disable placeholder <img alt="image"> fallback text leak from old
 *    list themes that rendered alt over background.
