Aurora Veil
Layered mesh of drifting colour fields behind a fine grain veil. Built on GPU-composited CSS gradients — a 60 fps full-page backdrop at 0 JS.
Ambience is a live light wash over the preview. Full palette re-theming of every demo arrives with Theme Studio (Pro).

lines 1–19 · v2.0.0No changelog entry mentions “Aurora Veil”, so the catalog records a single version for it.
Every line above is attributed to the single version this catalog records — we keep no per-line history, so no per-line attribution is invented. See the provenance page for the rule and the gaps.
Review notes · anchored to code lines
Threads attach to a line number in this asset's snippet, so a remark about the focus trap stays next to it.
Loading notes…
The snippet on this page is 19 lines long, so anchors run 1–19. Notes are per-asset and per-browser; a shared review thread is a server feature, and this panel is the local stand-in that proves the anchoring works.
Why it works — Three radial gradients drifting on a 16–20s clock with a grain pass on top. GPU-composited, zero JS, and the drift speed is slow enough to feel expensive.
When to skip it — Don't run full-page aurora behind content on every section — reserve it for one hero and fade it out by 60vh.

Theme Studio preview
Theming example — two token themes
Assets are token-driven (100% design-token driven). Here the same scene runs under two theme presets from the token sheet.
--accent 262 · dark surfaces
--accent 40 · paper surfaces
90-second read
Usage recipe — where this fits
Use it as the signature of a single screen — a hero backdrop, an entrance, a transition. One signature per screen; everything else stays quiet.
Compose it with calm content around it: the motion earns attention only when the layout does not compete for it.
Cost honesty
Performance note
Cheaper alternative — the static preview variant removes the animation loop and keeps the layout — a quieter, cheaper sibling.
What it needs
Browser support strip
No polyfills ship with the asset — if a listed feature is missing in a target browser, the graceful fallback is the static layout.
prefers-reduced-motion
Reduced-motion fallback
With prefers-reduced-motion: reduce, the animation loop and travel are removed; state changes keep working through opacity and colour (≤ 300ms). The demo you see above honours the switch — try it in your OS settings and the loop will quiet down.
Design rule: the reduced branch is a second design, not a stripped page — every state change stays visible.

Composition map — what pairs well
Same-family assets that compose cleanly with this one:
Halo Trail
Cursor trail of fading halos that also reacts to pressed state — an attention magnet for product demos. Pointer-events transparent, fully throttled.
AnimatedOrbit Deck
A 3D ring of cards/badges orbiting a focal chip with depth-of-field blur. Pause on hover, tilt with drag, auto-rotate for ambient showcase.
AnimatedStar Motes
Three-layer parallax starfield with twinkle variance and pointer drift. Canvas-free version included for quiet brand sites; WebGL tier for dense scenes.
One original micro-case
Inspiration context
The hero that held attention for one beat longer
A marketing page's hero used a stock fade-in that finished in 200ms — invisible to the eye, useless to the story. Re-timed with a slow settle (0.6s, ease-out-quart) and one typographic wipe, the hero read as 'alive' without a single new asset. The change was purely a curve and a delay.
Written in-house — no screenshots, no borrowed imagery. The pattern, not the pixels.

This asset belongs inside a bigger build — here is the prompt that would generate a page containing it:

Bundled dependencies — disclosed
Full snippet ≈ 1.1 KB raw, ~1 KB gzip — before any framework you already load.

Grab the asset as one file, ready to paste into your project.
Files are generated in your browser from the snippets on this page — nothing leaves the tab.
Scale, not clutter
Sizing system — three densities
Density is a token decision, not a per-page override — pick one density per product surface and hold it. Active: Default.
Runnable copy

Opens this asset in a new tab with its stylesheet injected — a real, editable HTML document in your browser. No account, no upload.
If the tab is blocked, use the single-file export instead — same content, saved locally.

This asset does not have a video yet — so the written version stands in: the code line walk below narrates the snippet line by line, and the design rationale on this page explains the default decisions. When a video ships, this exact panel hosts its full transcript.

Trade-off, visible
Size vs. quality slider
Standard · CSS + hover states
~6 KBadds transitions, focus-visible and reduced-motion rules
The slider is honest: the slim tier has no JS, the pro tier pays for behaviour. Start slim, upgrade only the surfaces that need it.
HTML → React, priced
Stack-switch cost note
Taking the HTML/CSS version into a React component costs real work — and the cost is predictable:
Event wiring
Hover, focus and click become handlers — the CSS stays, the state appears.
Props for the knobs
Every inline value that should vary becomes a prop with a default — the defaults must match the CSS exactly.
The estimate
A clean port of this asset is 20–45 minutes for a React developer — the 579-character stylesheet is the easy half.

Sibling comparison
| Compare | Aurora Veil | Halo Trail | Orbit Deck |
|---|---|---|---|
| Kind | Animated | Animated | Animated |
| Bundle | 2.6 KB gzip | 5.8 KB gzip | 9.7 KB gzip |
| a11y | 100/100 | 93/100 | 92/100 |
| Dependencies | none | none | motion |
| Copies / mo | 8,940 | 6,330 | 4,210 |
| Interactions | scroll | drag, hover | drag, scroll |
The honest verdict — Aurora Veil is the lighter default here; reach for Halo Trail when its extra weight buys an interaction this one lacks.

How these three were chosen: essays scored on shared tags (1 and 1 matches), then prompt scored on block/vibe overlap (1 matches). The rule lives in src/lib/spine.ts, so the same asset always links to the same three pages and a second reader can reproduce the choice.
