Found by driving Firefox 158 with real pointer, wheel and key input. - Time picker wheels used padding to reach the last rows. Firefox leaves bottom padding out of the scrollable area, so the last rows were unreachable and the 24H/AM/PM wheel could not scroll at all. Spacer pseudo-elements replace the padding. - Wheels can now be dragged with a mouse or pen, with inertia, a rubber-band at the ends and a spring back. Touch is left to the platform. - Theme changes no longer use a page-wide view transition. The snapshot could not blur what sits behind frosted glass, so every frosted surface went clear for the length of the cross-fade. - Dark shadows were invisible: black on a near-black canvas, with a deep negative spread tucking the blur under the element. The dark canvas is lifted, the shadows are stronger and the spreads milder. - Same-page links now travel (scroll-behavior: smooth, motion permitting). - data-nv-tristate: a checkbox that cycles unchecked, checked, partial; the browser can display a partial state but a click can never choose it. - Button groups show their pressed segment. GUIDELINES.md gains the cross-engine rules these defects taught, and makes Firefox the first browser to verify in. check.py, build.py and build.py --check pass.
