 ## [Unreleased]
 
+## [1.27.16] — 2026-07-07 — Offline that survives, and a faster first paint
+
+### Fixed
+
+- The installable app now survives being offline. A network failure on the auth probe was treated as a logged-out session — it wiped the offline caches and redirected to the login page, defeating the entire offline layer. Offline relaunches now render the dashboard from cache with the offline banner; only a real 401/403 or an explicit logout clears anything.
+- Chart text is readable in the light theme again — 23 chart surfaces drew their ticks and axis text in colours measuring near-invisible contrast; they now use the semantic text tokens (measured 13.2:1 in light, dark byte-identical).
+- On the mood insights page, correlation captions no longer escape their tiles on phone widths; the density guard now covers that route too. Row checkboxes gained a 32 px touch target at unchanged visual size.
+- The dashboard hero breathes: the score rings space at 24 px on desktop and the briefing section separates from the greeting row at the same rhythm as the card padding.
+
+### Changed
+
+- Every page sheds roughly 100 KB of compressed JavaScript: the translation catalog no longer ships twice (once per route bundle, once inlined into the page document — the dashboard document alone shrinks from 139 KB to 25 KB compressed); catalogs now load once as a cached static asset. All sixteen charts share a single chart runtime chunk instead of up to eight copies.
+- The dashboard's first paint carries real tile values straight from the server (measured −25 % largest-contentful-paint), and a new bundle-size budget gate in CI keeps route weights from regressing silently.
+
