Stored pages (generated at editor-save time) from before release 2026.11.5 carry
FeaturesGrid / Testimonials / NumberCounter grids without data-wsb-grid, so a
republish kept repeat(N,1fr) on phones (OLS home: body 594px wide at 360).
The <=767px block now matches the exact inline styles those emitters stored
(whole-attribute signatures; no spaces, as in git history and every stored
OLS/TTM page). Gallery shares the prefix with a free gap and keeps its columns:
the two colliding signatures carry :not(:has(> * > Gallery thumbnail)) in their
own rule (a browser without :has drops only that rule). Customer grids never
match. Mirrored byte-for-byte by WHP generateCompiledHTML (fix/legacy-grid-backend).
Tests: vitest selector contract (legacy shapes match, == current emitters minus
the hook, Gallery and customer grids never match, pretty == minified); head
parity pins updated; new real-browser suite test:browser:legacy-grid (Chromium +
Firefox, 360/390/768/1280) on the stored OLS home page + synthetic legacy grids;
colors suite folds the new rules back like the mobile-guard ones.
