Overview

Last Resort Font integration — pillar 2 of the v0.2 glyph strategy.

For codepoints whose Code Charts cell shows a placeholder box (unassigned, noncharacter, PUA), the chart glyph is drawn from Unicode’s Last Resort Font. The Last Resort Font ships as a UFO source with two parts that matter to us:

* `cmap-f13.ttx` — a Format 13 `cmap` that maps every codepoint
  (0x0..0x10FFFF) to a placeholder glyph name. 1,114,112 entries.
* `font.ufo/glyphs/*.glif` — 380 outline files, one per Unicode
  block + a handful of special types (`notdef`,
  `notdefplanezero`, the noncharacter / unassigned planes, …).
* `font.ufo/glyphs/contents.plist` — glyph name → `.glif` file.

The pipeline is read-only and stateless: cmap (cp → name) →contents (name → file) → glif (file → outline) → svg (outline →SVG document). No PDF parsing, no cell extraction, no border compositing — the placeholder outline is exactly what the Code Charts display.

See Source for how to locate the UFO on disk.
