The Atelier Design Law — premium, industrial-grade UI. Load BEFORE any UI/design work (pages, components, animations, icons, landing pages). Defines the style vocabulary, tokens, motion physics, component canon, reference canon, and the banned AI-slop anti-style.

Atelier's native asset tools — image→webp compression, video→webp frame sequences, scrollytelling scaffolding, and AI video generation (Gemini Omni Flash / Veo 3.1) with a graceful no-credentials fallback. Load when handling images, video, storytelling sections, or media generation.
Turn any component site, asset library, or API into something agents can use — a registry entry, a skill, or a full MCP server. Load when the user says "add this site/library to Atelier" or wants to contribute a new integration.
The Atelier operating loop — understand → clarify → plan → execute → review → compare-vs-done-state. Governs when to stop, when to ask, which model tier runs each phase, and when to think deep or compact. Load for ANY nontrivial task.
The thinking protocol — load FIRST on every prompt, before any other skill. Makes any model (Opus, Sonnet, Haiku) reason like a principal engineer - decisive answers, root-cause debugging, security reflexes, outcome-first communication. This is step 0 of the loop.
The design-truth gateway — resolves which design files are authoritative right now (core law + self-learning overlays). Run at the START of any UI/design task, before reading the design law.
The Atelier Auth Law — production-hardened session architecture (rotating refresh tokens, families, grace window, silent refresh, sliding window) plus the anti-patterns that corrupt auth. Load before designing or touching ANY authentication code.

When a prompt says "make it premium", it means exactly this document. If a
choice isn't covered, pick the calmer, quieter option. First run the gateway
skill — overlays in design_guide_versions may extend this law.
| Term | Meaning | Exemplars |
|---|---|---|
| Apple HIG | Clarity, deference to content, depth via layers | macOS, iOS |
| Editorial minimalism / Swiss style | Typography IS the design: strict grid, huge type-scale contrast, whitespace, near-monochrome, ONE accent | Linear, Vercel, Stripe |
| Glassmorphism (chrome only) | backdrop-blur panels for navbars/docks/overlays — never every card | macOS Big Sur |
| Enterprise motion choreography | Motion as physics system: springs, scroll-scrub, staggers | Cloudflare, Apple product pages |
| Scrollytelling | Scroll-scrubbed narrative scenes, pinned sections, frame sequences | Apple AirPods, Cloudflare home |
| Blueprint motif | Dotted/dashed hairline grid background, corner tick marks on cards, schematic diagrams | Cloudflare 2026 |
| Quiet depth | Depth from top-light insets and layering, not drop shadows | macOS windows |
#0B0B0C base, dotted blueprint grid with corner ticks framing
sections, ONE saturated accent (their orange) used for CTA bands and state,
massive grotesk display headlines ("Build without boundaries"), bento feature
cards with hairlines + live product mock terminals, full-bleed accent CTA
bands with floating outlined glyph cards, pill segmented pricing toggles,
logo-tab quote carousel, benefit ticker strip above the footer.--bg: #0A0A0B dark / #FAFAF8 light --bg-raised: #141518 / #FFFFFF
--ink: #F5F5F3 / #1A1A18 --ink-2: #9B9B98 --ink-3: #5C5C5A
--hairline: rgba(255,255,255,.08) / rgba(0,0,0,.08)
--accent: THE user's ONE brand color (project intake) — budget ≤10% of any viewport
Radius: 8 inputs / 12 cards / 16 modals / full pills. Spacing: 4-scale, ≥96px between landing sections.
Depth: layering + inset top-light `0 1px 0 rgba(255,255,255,.04)`; drop shadows ONLY on floating layers.
Type: grotesk UI/display (weights 400/500/600, -2% tracking on display), serif
italic for ONE emphasized phrase per major headline + big stats. Kickers: 11px
uppercase 0.14em --ink-3. Display: clamp(3rem, 8vw, 7rem). Data numerals:
tabular-nums.
Theming is centralized — NEVER hardcoded. Every color/radius/shadow lives as
a CSS variable in ONE place (globals.css / tokens file); components reference
semantic tokens (bg-background, text-ink-2, border-hairline), never hex
values or dark: one-offs per page. Dark, light, or any future theme = flip the
variable set on :root[data-theme] — zero per-page edits. A hardcoded color in
a component is a review failure.
cubic-bezier(0.16,1,0.3,1); interactive: spring {stiffness:260, damping:32, mass:0.9} — max one overshoot. Micro 150–250ms, element
300–500ms, scene 600–900ms; >1s only scroll-scrubbed.layoutId.prefers-reduced-motion → fades only. Animate transform/opacity/canvas ONLY.Lucide only, 1.5px stroke, 16/20/24, currentColor monochrome — never filled,
multicolor, or in colored circles. Accent only on state (verified/live/active).
Gaps → Phosphor thin or custom SVG on the 24px grid. Animated: Rive/Lottie,
monochrome+accent, single-loop. Emoji never in chrome. Illustrations: abstract
geometric blueprint motif (dot grids, wireframe globes, hairline schematics).
Product imagery: real UI in device frames on dotted-grid pedestals with corner
ticks — never fake dashboards. Fonts via Google Fonts (or system).
Card = raised surface, hairline, radius 12–16, 24px padding, top-light; header row = 36px bordered icon square + title + uppercase tag. Stat block = serif numeral over uppercase label, vertical hairline dividers. Nav = glass pill, condenses on scroll. Buttons: primary ink-filled pill (inverts on hover), secondary ghost hairline; ONE primary per view. Inputs: sunken + accent hairline focus glow. Tables: hairline separators, 11px uppercase heads.
Never hallucinate components. Query the registries first — shadcn/ui (MCP),
Aceternity (MCP), ReactBits (MCP), Motion.dev, MagicUI, Radix — then adapt to
these tokens. python <plugin>/db/store.py registry component lists what's
available.
