Overview

Style fields: weight, width, italic/bold flags, Panose family classification.

Returned fields:

weight_class, width_class, italic, bold, panose

ucode delta vs fontisan: the standalone ‘StyleExtractor` class is NOT ported. The OS/2 + head interpretation rules live inline here.

MECE: this extractor owns OS/2 + head. fvar-derived fields (axes, named instances, variable presence) live on the VariationDetail extractor (TODO 09).

Boundary: uses only ‘font.has_table?(tag)` and `font.table(tag)`. No class-specific branching — any SFNT-compatible font works.
