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.

Niveus — Dark appearance
|
|
--------------------------------------------------------------------------
|
|
Values for the dark side of every semantic role, resolved through
|
|
light-dark() in tokens/color.css. Like the light appearance, almost nothing
|
|
here is a literal color — every role is derived from --nv-brand.
|
|
|
|
Dark Niveus is warm graphite, not the light theme inverted. Surfaces get
|
|
*lighter* as they rise and each step is large enough to see; shadows are
|
|
deep and every raised thing carries a near-black contact line, because on a
|
|
dark canvas a shadow alone has nothing left to darken. The bevel is what
|
|
carries depth here — a lit top edge, a shaded bottom one — and filled color
|
|
stays saturated: a vivid accent with a light label reads as a lit key, not
|
|
as a hole.

/* --- Accent -------------------------------------------------------------
|
|
The same derivation as light: a fill is pushed out of the mid-tones until
|
|
its label clears 4.5:1, so the brand keeps its full saturation and a light
|
|
label. Earlier Niveus lifted the dark accent into pastel to avoid neon;
|
|
with bevel and sheen doing the shaping, a saturated fill reads as a lit
|
|
key instead, and the pastel was what made the whole system feel washed
|
|
out. Only the accent *text* (links, subtle labels) moves up the ramp,
|
|
because text on a dark canvas needs the lightness that a fill does not. */
