Overview

Renders one standalone per-block HTML gallery of missing glyphs at <face_dir>/missing/<BLOCK>.html (TODO 26).

Every touched block with at least one missing codepoint gets one page. The gallery is fully static — inlined CSS, no client-side fetch — so it works via file:// and is what fontist.org can iframe or screenshot for the "what's missing" widget.

SVGs are inlined from the co-located universal-set build (when GlyphPanel#available?). When the universal set is absent, the page renders codepoint IDs only — no errors, no broken-image placeholders.

For very large missing-codepoint sets (CJK can be thousands), the page emits at most page_size thumbnails inline; an overflow notice replaces the rest.
