Territory B editorial paper design system

GenCreator's visual system follows Territory B (New Creative Publishing), approved on 2026-08-22 (ADR-011 in gencreator.ai/docs/DECISIONS.md and starlight-design-intelligence/brand-packs/gencreator/DESIGN.md). Every release is treated as a small cultural object composed on warm uncoated paper stock with warm ink and a single spot-red registration mark.

Light paper and spot-color paletteCopy Anchor Link

Paper and ink carry at least 90% of every composition. Spot red (#c8322a) appears once per object to register an edition number, source note, active state, or human approval signature.

Typography systemCopy Anchor Link

Territory B separates editorial display, reading controls, and aligned technical metadata across three font roles:

1. Editorial display (Instrument Serif / Fraunces): Carries release titles, edition headers (.edition-display, line-height: 1.02, letter-spacing: -0.012em), and long-form editorial pull quotes (.prose-editorial in gencreator.ai/app/globals.css). Pinned font files (InstrumentSerif-Regular.otf and InstrumentSerif-Italic.otf, SIL OFL 1.1) are verified by SHA-256 in brand-packs/gencreator/SOURCE_AUTHORITY.md.
2. Reading and UI controls (Instrument Sans / Plus Jakarta Sans / Geist): Carries body prose, navigation, archival labels (.archival-label), and form controls (InstrumentSans[wdth,wght].ttf, SIL OFL 1.1).
3. Monospace metadata (JetBrains Mono / Geist Mono): Reserved strictly for source SHA-256 digests, timestamps, and code blocks—never used as decorative HUD chrome.

All headings and archival labels use sentence case ("Edition 03, released 22 April 2026", never EDITION · 03). text-transform: uppercase is banned on Territory B brand and marketing surfaces.

The allowAmbientGlow: false restraint ruleCopy Anchor Link

Unlike the dark-mode brands on this platform, GenCreator sets surfaceMode: 'paper' and allowAmbientGlow: false in docs-platform/lib/brands.ts. When BrandDocsLayout (app/[brand]/layout.tsx) renders a GenCreator page, it sets data-surface="paper" and data-glow="off" on the .lz-brand root container.

In docs-platform/app/global.css, those two attributes enforce three visual constraints:

1. Paper surface palette ([data-surface='paper']): Overrides Fumadocs CSS variables (--color-fd-background: #fbf9f5, --color-fd-foreground: #221f1b, --color-fd-card: #f4f0e8, --color-fd-border: #dfd9ce, --color-fd-primary: #c8322a).
2. Zero radial spotlight ([data-glow='off']): Hides the cursor-tracked radial glow pseudo-elements (.lz-spot[data-glow='off']::before, .lz-spot[data-glow='off']::after, and .lz-brand[data-glow='off'] .lz-spot::before/::after { display: none; }).
3. Crisp 1px border hover instead of glow shadow: On pointer devices, hovering a card, figure, or code block under data-glow="off" applies border-color: var(--brand-accent) (#c8322a), box-shadow: none, and a restrained -1px vertical lift.

Motion and texture budgets (gencreator.ai/design.md)Copy Anchor Link

• Photocopy grain (.paper-texture::before): Uses an inline SVG feTurbulence noise filter (baseFrequency="0.82", numOctaves="3", opacity: 0.055, dropping to 0.04 under prefers-reduced-motion: reduce), placed at z-index: -1 on paper containers and never behind body text.
• Timing tokens: --motion-quick: 120ms, --motion-standard: 240ms, and --motion-signature: 1100ms with --ease-gc: cubic-bezier(0.22, 1, 0.36, 1), maximum routine travel of 24px, and maximum stagger of 60ms.
• Surface-by-surface migration: In gencreator.ai, routes opt into Territory B via data-territory="b" after passing desktop, mobile, contrast, and reduced-motion verification.
