Release notes for 2.3.0.

Released: 2026-07-03

Host chrome-binding seams — new extension points let a host project inject markup and callables into the framework chrome without forking layout code: a chromeBindingsModule host-callables channel (ffedd8f4, #2501), docContentHeaderExtras and homeExtras binding slots (8e553706, #2500), and a createHomePageView factory exposed via the ./home-page subpath export with its own extras seam (20d728e8 / 34dfa5e7, #2502). HomePageView is re-exported from the host chrome adapter and adopted across package, showcase, and template home routes (40f88971 / 2f371ba6 / 3b9cea8d, #2503).
Accessibility contrast audit tooling — a contrast guard that checks the full color-pair matrix, with a --suggest mode that proposes OKLCH tweaks to clear WCAG floors (0f9668ad / 29d585e5, #2490, #2492).

doc-history: scope the rename-chain seal to the chain's physical path so unrelated files no longer share history (2520270b, #2517).
home-page: honor categoryMetaDir on the default locale (28da87c4, #2519).
chrome bindings: raise a loud error for an empty chromeBindingsModule and guard against a directory-valued path (8cea6c2b / 86c35b5d, #2518).
accessibility: burn down contrast failures across the dark presets and light schemes, retune 261 marginal pairs to a threshold+0.1 headroom, and audit muted/accent tokens on their real rendered backgrounds (57a16896 / d518d546 / 87a1d6b1, #2493, #2497, #2510).
e2e: randomize the workerd inspector port per fixture preview to fix a race under wrangler dev (fe9eceb6, #2084), and migrate fixture wrangler configs to Workers static-assets (a1c2f330).

doc-history: single-pass --name-status walk for the preBuild meta generation (07a98c11, #2517).
home-page: extract prepareHomeData and shrink six adapters (c9c4e765, #2519).
deps: bump the zfb family to 0.1.0-next.75 (9e305f5d, #2511).
docs: document the host chrome-binding seams (EN + JA) and add the color-scheme-a11y project skill (31a69ce5 / 33c04519).
