/* herdr-design-system — canonical light theme tokens (Spec §6-16, §92).
 *
 * Light, neutral, clean, ChatGPT-inspired developer UI. White surfaces, light
 * gray backgrounds, subtle borders. Inter for UI, monospace only for
 * terminal/code/paths/IDs/hashes/logs.
 *
 * Status is NEVER communicated by color alone — every color token pairs with a
 * label/icon in the consuming components (see herdr-web-components).
 *
 * Tokens are plain CSS custom properties so they work with any component
 * model (Web Components, or a build-time framework) with no build step.
