The DOM-dump script is an arrow function, not a self-calling IIFE: Aside's `pg.evaluate($_DUMP)` receives the function and runs it in the page (the IIFE form executed in the repl sandbox, where `document` does not exist), and the fallback engine calls it with `$B js "($_DUMP)()" --out --raw`. Hygiene widens to every URL-bearing attribute (src, srcset per candidate, poster, action, formaction, data, ping, cite lose their query strings and fragments) and to data: URLs inside existing <style> nodes. The persist and scan blocks restate REPORT_DIR and RUN_ID literally instead of relying on a shell variable from an earlier block; the baseline's targetSet is defined per mode (repo-relative paths in source mode, page slugs in DOM mode) so DOM-mode deltas can match; the PR-body Detector line lists the states the probe can actually print. The DOM fixture is re-captured with the new script from outside the repo (the engine walks up from cwd for DESIGN.md, which the metadata now records). Doctrine contradictions the design specialist found: the landing-page motion rule matches the one-authored-moment reflex; the background rule names the catalog's halo/spotlight/stripe/grid slop instead of asking for gradients; the universal font rule is scoped to the display voice with the body/UI exceptions; "two typefaces max" allows the mono; the methodology's banned-font line renders BANNED_FONTS; Courier New is banned outright; the Brutalist, Retro-Futuristic, and Playful menu entries stop recommending system stacks, glow, and bounce; the coherence nudge uses the decoration vocabulary; Path A's gate names the display voice; font-loading prose points at the source the procedure verified; centered-everything is MEDIUM (an aggregate heuristic); the mockup guard reads "Never by default (unless the brief above asks for it)". The checklist's AUTO-FIX list renders the catalog's auto-fix rules; category 9 and the Hard Rules pointer count from the same partition helpers (detectorSlopEntries, judgmentTellEntries); the handoff list renders from HANDOFF_COMMANDS; a missing catalog id fails gen-skill-docs by name. gstack's own DESIGN.md gains border tokens and Decisions Log rows for its live-feed pulse and 11px mono labels. frontend-scope is case-sensitive like the bash arm. gen-skill-docs shares one emitGenerated helper for sections and lib-derived assets; renderCatalog keeps the one style with a caller. Tests: shared sliceBetween that fails on a missing end marker, the slop-gate fixture's real end marker, an isolated browse daemon for the DOM-mode E2E, the DOM hygiene test gated to CI or opt-in, docs notes for the two superseded plan sentences.

Design System — gstack
Overview
-
What this is: Community website for gstack — a CLI tool that turns Claude Code into a virtual engineering team
-
Who it's for: Developers discovering gstack, existing community members
-
Space/industry: Developer tools (peers: Linear, Raycast, Warp, Zed)
-
Project type: Community dashboard + marketing site
-
Direction: Industrial/Utilitarian — function-first, data-dense, monospace as personality font
-
Decoration level: Intentional — subtle noise/grain texture on surfaces for materiality
-
Mood: Serious tool built by someone who cares about craft. Warm, not cold. The CLI heritage IS the brand.
-
Reference sites: formulae.brew.sh (competitor, but ours is live and interactive), Linear (dark + restrained), Warp (warm accents)
Colors
- Approach: Restrained — amber accent is rare and meaningful. Dashboard data gets the color; chrome stays neutral.
- Primary (dark mode): amber-500 #F59E0B — warm, energetic, reads as "terminal cursor"
- Primary (light mode): amber-600 #D97706 — darker for contrast against white backgrounds
- Primary text accent (dark mode): amber-400 #FBBF24
- Primary text accent (light mode): amber-700 #B45309
- Neutrals: Cool zinc grays
- zinc-50: #FAFAFA (lightest)
- zinc-400: #A1A1AA
- zinc-600: #52525B
- zinc-800: #27272A
- Surface (dark): #141414
- Base (dark): #0C0C0C
- Surface (light): #FFFFFF
- Base (light): #FAFAF9
- Semantic: success #22C55E, warning #F59E0B, error #EF4444, info #3B82F6
- Dark mode: Default. Near-black base (#0C0C0C), surface cards at #141414, borders at #262626.
- Light mode: Warm stone base (#FAFAF9), white surface cards, stone borders (#E7E5E4). Amber accent shifts to amber-600 for contrast.
Typography
- Display/Hero: Satoshi (Black 900 / Bold 700) — geometric with warmth, distinctive letterforms (the lowercase 'a' and 'g'). Not Inter, not Geist. Loaded from Fontshare CDN.
- Body: DM Sans (Regular 400 / Medium 500 / Semibold 600) — clean, readable, slightly friendlier than geometric display. Loaded from Google Fonts.
- UI/Labels: DM Sans (same as body)
- Data/Tables: JetBrains Mono (Regular 400 / Medium 500) — the personality font. Supports tabular-nums. Monospace should be prominent, not hidden in code blocks. Loaded from Google Fonts.
- Code: JetBrains Mono
- Loading: Google Fonts for DM Sans + JetBrains Mono, Fontshare for Satoshi. Use
display=swap. - Scale:
- Hero: 72px / clamp(40px, 6vw, 72px)
- H1: 48px
- H2: 32px
- H3: 24px
- H4: 18px
- Body: 16px
- Small: 14px
- Caption: 13px
- Micro: 12px
- Nano: 11px (JetBrains Mono labels)
Layout
- Approach: Grid-disciplined for dashboard, editorial hero for landing page
- Grid: 12 columns at lg+, 1 column at mobile
- Max content width: 1200px (6xl)
- Border radius: sm:4px, md:8px, lg:12px, full:9999px
- Cards/panels: lg (12px)
- Buttons/inputs: md (8px)
- Badges/pills: full (9999px)
- Skill bars: sm (4px)
Spacing
- Base unit: 4px
- Density: Comfortable — not cramped (not Bloomberg Terminal), not spacious (not a marketing site)
- Scale: 2xs(2px) xs(4px) sm(8px) md(16px) lg(24px) xl(32px) 2xl(48px) 3xl(64px)
Motion
- Approach: Minimal-functional — only transitions that aid comprehension. The dashboard's live feed IS the motion.
- Easing: enter(ease-out / cubic-bezier(0.16,1,0.3,1)) exit(ease-in) move(ease-in-out)
- Duration: micro(50-100ms) short(150ms) medium(250ms) long(400ms)
- Animated elements: live feed dot pulse (2s infinite), skill bar fill (600ms ease-out), hover states (150ms)
Grain Texture
Apply a subtle noise overlay to the entire page for materiality:
- Dark mode: opacity 0.03
- Light mode: opacity 0.02
- Use SVG feTurbulence filter as a CSS background-image on body::after
- pointer-events: none, position: fixed, z-index: 9999
Decisions Log
| Date | Decision | Rationale |
|---|---|---|
| 2026-03-21 | Initial design system | Created by /design-consultation. Industrial aesthetic, warm amber accent, Satoshi + DM Sans + JetBrains Mono. |
| 2026-03-21 | Light mode amber-600 | amber-500 too bright/washed against white; amber-700 too brown/umber. amber-600 is the sweet spot. |
| 2026-03-21 | Grain texture | Adds materiality to flat dark surfaces. Prevents the "generic SaaS template" sameness. |
| 2026-09-08 | Open DESIGN.md format | Converted with gstack-design-md convert: tokens in front matter, canonical sections, Motion and Decisions Log kept as extras. DM Sans stays the body face: it sits on the overused-as-display list, and body/UI use on an Operate surface is the allowed exception under the role-scoped rule. |
| 2026-09-08 | Live-feed pulse is the one authored motion moment | The dashboard's 2s pulse on the live-feed dot is the page's single authored motion, so it stands as an intentional exception to the pulsing-dot catalog rule; every other surface keeps state changes static. |
| 2026-09-08 | JetBrains Mono labels at 11px | The mono personality font runs on labels at 11px (Nano), below the 12px UI-text floor; an intentional exception recorded here so the detector's undersized-ui-text and monospace-costume rows are read as decided, not open. |
