Found via live browser testing of the first consumer (e-ink skin):
- An extension-registered skin selected by the user was lost on reload: both
the pre-paint inline script in index.html AND the boot-time appearance sync
normalized the persisted skin against the (extension-less) known-skins list
and clobbered localStorage back to 'default' before the extension's
registerHermesSkin() could run. Both sites now PRESERVE an unknown non-default
persisted skin (a likely pending extension skin), so it survives the reload
and the extension re-applies it on load. The server push is skipped for a
still-pending ext skin.
- Expanded the token allowlist to the full accent family
(--accent-hover/-text/-bg/-bg-strong/-rgb + --surface-subtle) so a skin can
fully recolor accent-driven chrome (active rail, chips, profile labels), not
just --accent. Value regex now also accepts a bare RGB triple for --accent-rgb.
Regression tests added for both preservation sites. Full suite: 10876 passed.
