/* ============================================================================ Memstead — shared brochure design system (memstead.com + memstead.io) SINGLE SOURCE: websites/shared/brochure/styles.css. Each site's npm predev/prebuild copies this sheet (plus fingerprint.js and fonts/) into its public/ via ../shared/brochure/sync.sh — those public/ copies are generated and gitignored; edit only this file. The registry embeds the .io build output, so it inherits the synced copy automatically. Homestead + blueprint: warm paper, structural indigo, one accent per surface. Default accent = forest-sage green (.com). The .io pages add class="io" on to switch the accent to harvest gold (see html.io below). The .ai runtime has its own system — light cool-mist + royal blue. See SPEC §2 Palette. Type duality: humanist sans for prose, mono for structure, serif for brand. Hard rules (from SPEC §2): no particle constellation, no neon gradient. ============================================================================ */ /* Self-hosted webfonts (variable Fraunces / Inter / JetBrains Mono), synced to /fonts/ alongside this sheet.
