/* Heddle design tokens: Heddle linen (Daniel, 2026-10-18).
   Source of truth for the Heddle Online browser app and the plugin's library page (CONTRACTS.md I-8).
   Change here first; online owns this file, dev consumes it.
   Fonts: Literata for titles and reading text, IBM Plex Sans for controls, IBM Plex Mono for labels.
   Shipped code self-hosts the fonts (no third-party requests); prototypes may load Google Fonts.
   Mark: docs/workstreams/dev/brand/heddle_mark.svg (stroke currentColor; colour it with --ink). */
