Clean Light — Pack Aesthetic #

The appearance reference for the clean-light Pack — the catalog's first light-field pack. syntax is warm dark paper, editorial-mono is cool print with dark-piece fields, crt-terminal is emissive glass; Clean Light is a white studio: soft-neutral fields, white cards separated by thin rules and a quiet layered shadow, one confident product blue. The design-YouTuber / product-demo voice. The engine and Pipelines are identical; only the dress changes. This doc is what the Critic verifies a clean-light Preset against.

Every load-bearing value below was measured at intake (2026-07-13), not remembered: field/card whites and the quiet-shadow ramp from notion.com, the hairline and cool-ink family from docs.stripe.com, the Geist voice and mono-eyebrow label grammar from vercel.com. Register references: product launch pages, tool-demo videos, design-YouTuber b-roll — Notion, Stripe, Vercel, Linear, Figma community.

Channel Voice #

Calm, confident, effortless. The mood is "product film," not "keynote" — nothing shouts, nothing decorates. Negative space is the main material: generosity of margin IS the luxury cue. Where Syntax is hand-made and Editorial Mono is art-directed print, Clean Light is studio-made — every object photographed on a white sweep under flat, even light.

Palette — neutrals plus one blue #

• One accent. Blue does every accent job — kicker, pin, active cue, every annotation tool. An alert is the same blue doing a louder job, never a second hue. (Q4: this pack idles at ONE saturated hue.)
• No warm anything. The neutral ladder is cool; warmth belongs to other packs.

Type System #

Geist + Geist Mono (self-hosted via @fontsource in src/lib/packs/clean-light/fonts.ts; both ship true cuts — never synthesize).

• Geist — display and body: titles, names, quotes. 600 semibold is the display ceiling (the register is understated — vercel's h1 measures 400); hierarchy comes from size and the ink/slate split, never from heavy cuts.
• Geist Mono — the eyebrow-label voice: kickers, tags, stamps, diagram labels. 0.07em tracking (measured: vercel's mono eyebrows at 1px/14px), weight 400–500. Sentence case stays the default — this pack does not shout; uppercase belongs only where a pipeline's label voice is intrinsically caps.

Surface Treatment — the white studio #

The structural claims, and the roles they exercise:

• Depth is a quiet float. depth-treatment is a straight-down, wide-blur, low-alpha shadow (0 8px 36px rgba(9,13,20,0.10) @4K — notion's measured 4-layer ramp, scaled and lifted a step for broadcast). The "screenshot floating on white" read. No stepped stacks, no glow, no gaussian drama.
• Rules are thin. Card boundaries are #e3e8ee hairlines at ~1px 1080 equivalent (0.18cqmin @4K — thinner vanishes on downscale). The border whispers; the shadow does the separating.
• Edges are die-cut. edge-treatment: 'clean' — nothing tears, feathers, or fibers.
• Light fields everywhere. Full-frame pieces sit on the near-white studio gradient; every additive atmosphere role (keys, glows, bands, motes) is zeroed. Flat, even light is the claim — a staged key would make it a set, not a studio.
• Ink needs no armor. Baked glyph text-shadows are claimed off — dark ink on white needs none, and a dark halo on white reads as a bug.
• Substrate ≠ chrome binds as everywhere: quoted documents keep their own physics; the white-card grammar is only what the channel adds.

Motion Vocabulary Preferences #

A subset of the shared vocabulary, biased to effortless: smooth fades and micro-scale resolves (the product-film cut), settled-place at low overshoot (objects set down gently, never tossed), stroke-draw for thin diagram rules, cursor moves as first-class content (the screencast register). Exits dissolve or slide short distances. Avoid: bounce, wobble, tape-down physics, typewriter pop-in, anything that reads as effortful.

Sound: soft, short, dry — felt ticks and low thumps at the quiet end of the kit. Audition samples; event names lie.

Anti-Aesthetic — what Clean Light is not #

• No dark fields. A near-black backdrop under a clean-light piece is a pipeline bug by definition — this is the catalog's light pack.
• No chunky borders, no stepped hard-offset shadows — that grammar is syntax's property.
• No gloss: no gradients-as-atmosphere, no flares, no glassy plates, no vignettes. White is flat.
• No grain, grit, or paper tooth — the studio is digital-clean. (Paper-grain effects that bond a dark field read as dirt on white.)
• No torn edges, tape, or collage — nothing is stuck down in a studio.
• No second saturated hue; no warm tints. One blue.
• No heavy cuts (700+ display), no letterspaced shouting beyond the eyebrow grammar, no all-caps titles.
• Not sterile-corporate: generous space and real content keep it human; if a frame reads as a slide template, the composition is wrong, not the pack.

When in doubt: would this frame pass as b-roll in a top-tier product film?
