| description | Guides the design, layout, styling, and interactivity of kernel.chat editorial spreads and standalone artifact editions. Use this skill when editing or creating pages, React components, CSS files, or single-file HTML artifacts in the kernel.chat project to enforce the POPEYE-inspired bilingual design grammar and the interaction-language/artifact-language laws. |
Kernel Chat Web Design
Overview
This skill encodes the visual grammar, interaction constraints, styling tokens, and publishing guidelines of kernel.chat. It serves as the single source of truth for creating editorial magazine issues that honor the POPEYE-inspired warmth while remaining calm, accessible, and scientifically honest.
Skill Routing
Use this skill as the implementation and publication contract. Pair it with the specialist that matches the phase:
- Use
$kernel-chat-art-direction before implementation when the visual concept, cover, composition, type hierarchy, asset grammar, or responsive transformation is not yet resolved.
- Use
$motion-design, $micro-interactions, or the relevant GSAP skill when motion requires detailed choreography beyond the house constraints below.
- Use
$kernel-chat-design-qa after implementation for rendered desktop/mobile inspection, accessibility and motion checks, print proof, and live-production verification.
Do not collapse these phases into a single styling pass. Art direction decides the visual argument; this skill implements it in the house system; design QA proves the result.
The House Grammar
kernel.chat is an editorial magazine, not an application. Every release is named ISSUE N · MONTH YEAR.
Voice & Copy Constraints
- Never name the inspiration on the site. No mention of "POPEYE" in user-visible copy. Homage is carried entirely through grammar.
- Magazine terminology only. Use terms like issue, feature, spread, folio, kicker, monument, colophon, masthead, dateline, bulletin. Do not use app terms like dashboard, panel, card, widget, modal.
- Typography. EB Garamond for prose, Courier Prime for metadata, Noto Serif JP for Japanese subtitles and parallel text.
- Bilingual Lockups. EN-primary with selective JP subtitles/lockups (
.pop-bilingual > .pop-latin / .pop-jp).
- No Emojis. Use the star/asterisk symbol (★) as the single recurring folio system glyph.
Core Design System & Tokens
CSS custom properties live in src/index.css (specifically lines 118-150 for tokens). Do not hardcode values; always use these variables.
The Stock Cabinet (Paper Grounds)
--pop-ivory (#FAF9F6) — Serious-sober / press-preview white ground.--pop-cream (#F3E9D2) — Warm default magazine paper.--pop-butter (#EFD9A0) — Summer / slow leisure reading paper.--pop-kraft (#C8A97E) — Camel / outdoor field-report paper.--pop-sepia (#D4C5A9) — Muted background accent.--pop-coffee (#6B4E3D) — Rich brown text / neutral accent.--pop-ink (#1F1E1D) — Night / nocturnal dark mode ground.--pop-ledger (#F2EFE2) — Pale graph-ruled paper for audit issues.
The Ink Cabinet (Spot Accents)
Declaring an accent shifts the Spot Color (--issue-accent-base and derived tones via oklch). Raw hexes are permitted if they pass isPopeyeSafe() (rejects gray, neon, and RGB primaries).
| Seed | Base Hex | Fits / Temperament |
|---|
tomato | #E24E1B | The default house accent. 370+ issues. |
brick | #9E3A2B | Deeper, archival — literature, memory, record-of-record. |
cobalt | #1D4E89 | Winter, nocturnal, nightlife, city transit-blue. |
pool | #4FB5C8 | Teal — systems, terminal, code, infrastructure. |
ivy | #2E4A2E | Deep forest — nature, outdoor, agriculture. |
olive | #6B7A3D | Fatigue-olive — field work, labor, maps. |
celadon | #6F968A | Muted grey-jade (비색) — Korean lifestyle / yeobaek (negative space). |
amethyst | #6B5B95 | Metapage / anniversary / year-in-review. |
oxblood | #5E2328 | Burgundy — literature, wine, memory, endings. |
coffee | #6B4E3D | Rich brown — craft, conversation, slow work. |
graphite | #3F3D3A | Pencil-lead grey — audits, ledger-books. |
The Interaction Language
Interactive elements must obey The Seven Rules from docs/interaction-language.md.
- Calm by Default. Touches deepens; it never gates. The page at rest is complete.
- Calibrated Instruments. Controls represent a variable the story is about. No hover effects, cursor trails, scroll-triggered fades, or decorative animations.
- Motion is Weather. CSS-only transitions and keyframes at weather amplitude (movement of paper in a room).
- Exception: Working-Model Plate. Script-driven animation (
requestAnimationFrame) is allowed only inside a framed plate, must be timer-robust (race rAF with setTimeout), and must collapse instantly to resting state under prefers-reduced-motion.
- Everything Stays on the Page. Every state exists in the DOM at all times. Print (
@media print) must stack all states. Generative plates must print their deterministic seed (No.###) on the artwork so they can be re-drawn.
- Established ARIA Patterns. Roving tab-index radiogroups, switch, tablist/tabpanel, standard button toggles. Focus states must use the issue accent and remain visible on all stocks.
- The Meter Tells the Truth. No faked gauges or progress bars. Displayed numbers are measured, or labelled representative next to the number (
meterNote / plateNote). Ledgers are session-only and unrecorded.
- Two Instances Before a Pattern. Do not extract shared machinery until a second story absolutely requires it.
The Thirteen Interaction Shapes
- Dial (
instrument, ARIA radiogroup): N ordered positions on one variable.
- Compare (
compare, ARIA switch): A binary toggle between two co-equal lenses.
- Sequence (
sequence, ARIA tablist): An ordered process in discrete, complete stages.
- Galley (
galley, ARIA pressed toggles): Passage-level strike/stet editorial marks.
- Margin (
margin, native textareas): Writable session-only margins for notes.
- Press (
press, composition sliders): Composing stock, ink seed, and layout.
- Close (
close, sibling buttons): A feed with an equal-weight stop control.
- Proof (
proof, line adjudication): Adjudicating machine drafts (keep / edit / strike).
- Day (
day, moment selectors): Marking time-lived moments (LET IT RIDE / STEP IN).
- Plate (
plate, block simulation): Operational blocks with wires, redraws, and seeds.
- Bore (
bore, gauge WINCH button): Vertical strata probe with carried context.
- Fourier (
fourier, canvas phasor): Harmonic wave summation and Web Audio preview.
- Audit (
audit, proximity beam): Attention metering, proximity-mask spotlight, and budgets.
- Composite: Tutor (
tutor, lesson frame): Composes primitives to teach interaction.
Standalone Artifact Editions
Every issue ships both as a site spread and as a standalone Artifact Edition (artifacts/<N>-<slug>.html).
The Artifact Grammar
- One Self-Contained File. Strictly CSS-inline, strict CSP-safe, no external CDNs or scripts. Font stacks must utilize local fallbacks.
- The Depth Doctrine. Must go deep vertically (axis with a gauge, carried context from upper layers, floor that pays, emphasis-never-existence).
- Tactile Physics. Dragging or shifting should use interruptible spring physics, inertia, friction, and lag rather than linear bezier curves.
- Disclosures. Running head, colophon, and notes explaining that data is session-only and reload erases it.
Verification & Publishing Workflow
Always run verification commands before merging/shipping:
npx tsc --noEmit
npm run build
npm run dev
