Theme: light is a dimmer brand-tinted stone with deeper shade, so it reads as the same material as dark; every neutral now carries --nv-brand in both appearances. Native controls (accent-color, caret-color) take the brand. Time picker: 24-hour by default; data-nv-format-toggle adds a third wheel of 24H / AM / PM. Swiping it rebuilds the hour wheel for the new format. The selection lens is a raised glass bar, not a flat band. Motion: drum effect on the wheels as a scroll-driven animation, with a script fallback for engines without it (Firefox); rubber-band at both ends of a wheel that springs back; calendar months slide locally instead of via a page-wide transition; a chosen day springs into place. Firefox: wheel notches arrive in lines, not pixels, which made the rubber-band invisible; deltaMode is now normalised. The selected-day pop no longer plays on page load. Also: hover only inside @media (hover: hover) on the slider, the Glaze inner glow is a token, and the focus note in GUIDELINES.md is corrected (popovers do not trap focus). SPDX identifier added to niveus.js. check.py, build.py and build.py --check pass. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Niveus — Materials
|
|
--------------------------------------------------------------------------
|
|
A material is a surface treatment: what it is made of, not where it sits.
|
|
Elevation answers "how far from the canvas"; material answers "what does
|
|
light do when it hits this".
|
|
|
|
solid opaque, stable. The default. Content lives here.
|
|
elevated solid with depth and a top highlight. Separated from context.
|
|
inset recessed into its parent. Fields, wells, tracks.
|
|
frosted translucent, moderately blurred, bevelled. Chrome that sits
|
|
over content: bars, docks, launchers, notifications, menus.
|
|
glass more translucent, lightly blurred. Contextual layers where the
|
|
content behind should stay legible: overlays, hover cards.
|
|
glaze glass with a dial. How frosted it is belongs to whoever is
|
|
looking at it, so it is one number (--nv-glass-frost) rather
|
|
than a fixed recipe, and it carries a rim that catches the
|
|
light and follows the pointer.
|
|
|
|
Niveus is a solid system with glass used sparingly. Windows, cards, dialogs
|
|
and everything that holds content are solid; translucency is reserved for
|
|
the chrome that floats over them. Translucency has a cost — it tints
|
|
whatever is behind it and forces the GPU to composite — and used everywhere
|
|
it stops meaning "this floats".
|
|
|
|
Sheen is the light falling across a raised face. It is laid over a
|
|
surface's own color as background-image, so a surface keeps its role color
|
|
and gains the gradient; anything that does not draw gradients simply shows
|
|
the role color.

The one input the glaze material derives from: 0 is clear glass, 1 is

change just that region, or bind a slider to it with data-nv-var and let

the person looking choose. The glaze recipe reads it where it is used,
