mtlcl410andClaude Opus 5.5 f2e222ebc5 M2: a non-embedded CIDFont's fallback request carries its descendant's font descriptor (ISO 32000-2 §9.7.4, §9.8)
Type0Font::new built its FallbackFontQuery from the Type 0 font
dictionary, which has no /FontDescriptor (ISO 32000-2 §9.7.6.1,
Table 119); the descriptor belongs to the descendant CIDFont (§9.7.4.1,
Table 115). Every request for a non-embedded CID font therefore said
not serif, not italic, weight 400, and no resolver could tell a Song or
Mincho font from a Hei or Gothic one, or see /FontWeight 700 (§9.8,
Tables 120, 121).

FallbackFontQuery::with_descriptor takes the name from the font
dictionary and the style from the given descriptor; new() calls it with
the dictionary's own descriptor, so simple fonts are unchanged. The CID
path passes the descendant's descriptor it already reads.

Vendored hayro-interpret patch (58). Tests in
crates/render/tests/it/cid_fallback_query.rs record the request a
font_resolver receives. The CID-fonts parity note now says the Japanese
face also follows the Serif flag and /FontWeight.
