Layer names (and any other UI text) in scripts the bundled Inter lacks
showed missing-glyph boxes even when the canvas found a fallback font.
The lazy UI loader only knew CJK plus a short hard-coded list of Thai
font paths, so any other script, or a Thai font at another path, never
got a fallback.
photocraft_text::scripts classifies 20 scripts and picks candidate files
by name (Noto, Windows, macOS and common Linux families) from a listing
of the platform font directories, made once per process on first need.
The UI loader tries a script once when one of its characters is missing,
reads at most a few candidates, and registers the first face whose cmap
really maps the character. Latin text loads nothing; the web build has
no candidates and does nothing.
