#3220: redesign generated-image rendering from a permanent bordered card
(filename + Open/Download buttons) to a clean inline image with click-to-zoom
lightbox + a hover/focus-revealed Download overlay, matching ChatGPT/Claude/
Gemini. Drops redundant Open (lightbox already covers it). Tests updated.
#3337: fix two-tone code background — Prism's prism-tomorrow theme styled the
parent <pre> gray while the <code> was navy var(--code-bg), so dark theme showed
a gray frame around navy code. Override BOTH .preview-code[class*=language-] and
its <code> to var(--code-bg) (mirrors the chat code-block fix at .msg-body pre).
#3223: fix action-menu clipping — the new Regenerate-title row made the 9-item
menu tall enough to overflow the viewport bottom when opened on a top-anchored
row at short viewports (e.g. 1280x720). _positionSessionActionMenu now clamps
the menu within both viewport edges and caps max-height with scroll when the
menu is taller than the viewport.
