cayce a282aedb94 lint: wrap long lines (E501), fix F841/F821/E731 — make check fully green
All 32 findings resolved: regex literals kept single-line with noqa
(pattern IS the reviewed artifact), HTML rows string-concatenated for
line length, walrus tuple in BIP-340 verify split into named generator,
unused pytest import dropped. No behavior changes; 44/44 tests pass.
Full-gate discipline restored: ruff exit 0.

"""Brand image templates (Pillow). 1080x1350 portrait, two brand styles.
Deterministic, template-driven graphics — deliberately not AI-generated media
(DECISIONS: nothing here trips AI-media disclosure requirements; it is typeset
design). Fonts: Pillow's bundled default (scalable), so no system font deps.
