Tokens - --nv-color-glow role (light and dark) and a glow scale: --nv-glow-sm/md/lg, --nv-glow-blur-*, --nv-glow-spread-*, --nv-glow-strength - --nv-stagger (0ms under reduced motion) and --nv-duration-shimmer Components - Card: --lit (lit top edge in --nv-card-tint), --glow, --spotlight (light follows the pointer); light layers combine with every elevation - Tile: small raised key for a glyph or product mark; --solid, --glow, sizes - Avatar: raised disc with --ring / --glow, sizes, __status, avatar group - Stat: readings set into one recessed well (.nv-stat-group) - Steps: markers set into a rail; done steps light their stretch; vertical - Deck: one surface in front of stacked layers of its kind - Skeleton: recessed placeholder with a slow sweep, still under reduced motion - Text: .nv-text-lit and .nv-text-lit--accent Continuity - .nv-reveal / .nv-reveal-group: content arrives once as it scrolls into view (nv-arrive keyframe); niveus.js marks pending state, so nothing is hidden without the script or under reduced motion - niveus.js tracks the pointer for .nv-card--spotlight README and REFERENCE document every new class, token and attribute; tools/check.py passes and dist/ is rebuilt.

One surface in front of others of its kind: the current item of a set that
|
|
has more behind it. The layers are cards seen edge-on, stepping back and
|
|
dimming with distance, so the set has depth without anything having to
|
|
move. Use it where "there are more of these" is part of the message — a
|
|
showcase of products, a stack of notifications, a carousel at rest.
|
|
|
|
Everything in the deck shares one grid cell. The front surface is any
|
|
element; the layers are decorative and hidden from assistive technology.
|
|
Panels that swap (an .nv-tab-panel set) can live in the deck together:
|
|
the hidden ones take no space.
