#6830 f8c4334 - perf: run the text shimmer on the compositor without duplicate markup (@rupic-app)
where -webkit-mask-clip: text is supported the host is masked and an additive band moves on translate, so a shimmering label no longer repaints its glyphs every frame; other browsers keep the gradient fallback. the band travels the same distance as the fallback, so shimmer-speed, shimmer-duration, shimmer-repeat-delay, shimmer-angle, and shimmer-container produce the same sweep on both paths. it defaults to white and takes --shimmer-color, shimmer-color-*, and shimmer-invert, which matches the fallback on white and dark surfaces and can differ on tinted ones. the host mask clips every descendant, so a text shimmer host must contain text only. text shimmer now holds still under prefers-reduced-motion: reduce on both paths; shimmer-bg is unchanged.
#7083 4e5d2b3 - docs: align the documented utilities and defaults with the shipped CSS (@Kinfe123)
#6829 5d6638f - fix: gate the text clip behind the same capability check as the gradient, so shimmer text stays readable below the browser support floor (@MFA-G)
