v0.3.0.20 — Overlay and layout fixes

[0.3.0.20] — 2026-07-07

Fixed

• Messages overlay (i18n) — messages-panel.js defined LatchI18n only inside a click handler while loadPanel()/closePanel() referenced it at module scope; opening Messages threw ReferenceError: i18n is not defined and AJAX feeds never ran (v0.3.0.19 regression).
• Admin overlay history — closing the account/admin panel after in-panel navigation now walks back the full history stack (overlayPushDepth) so refresh no longer lands on the last admin URL.
• Header vs main width — public header, main, and footer share one column rule (.latch-header .header-bar included); header no longer renders wider than topic/board content when guest cache omits page-forum.
• Pinned badge contrast — dark theme badge tokens (--badge-fg / --badge-bg) meet WCAG contrast on pinned labels (default + modern themes).

Changed

• md-import images — HTML <img> / <picture> tags and foreign-host markdown images convert to a CDN placeholder (/.md-import/REPLACE-ME.png) so imports pass image-upload BodyGuard and can be swapped in the editor.
• Apache packaging example — packaging/latch-httpd.conf documents ServerAlias www.forum.example.com.
