Colors: oklch()/oklab() and color-mix(); linear-gradient backgrounds. Grid: named-line placement, repeat() expansion, drop whitespace-only grid items; upgrade taffy 0.7 -> 0.12 so aspect-ratio images in auto-height rows no longer collapse to slivers. CSS: @layer, nesting, @property, :is()/:where(), clamp(), @media not all; source/track/param/area and svg desc/metadata as display:none. Images: webp + intrinsic sizing, srcset/picture, browser UA + Accept for CDN fetches, grey placeholder on failure; width/height HTML attributes rank below author CSS with aspect-ratio preserved for auto axes.
