 * Vigor public documentation — standalone stylesheet.

 * These are static, crawlable, zero-JS marketing/docs pages served straight

 * brand palette used by the SPA Landing page (frontend/src/views/Landing.vue),
 * porting its tokens + "sketch" aesthetic here so the docs feel like the same
 * product without importing the Vue app. Colour is NEVER used alone — every
 * status/score signal is paired with a Material Symbols icon and a text label.
