/* ==========================================================================
   Onyx Next design system, as used by the public sample workspace (/sample/*).
   Direction: dark-first "onyx" surfaces, one accent (Pulse Blue, taken from the
   Onyx Insights logo), Geist + Geist Mono, hairline depth instead of shadows.
   Structural reference: Linear (awesome-design-md). Borrowed ideas: the surface
   ladder, hairlines, product-first framing, 8/12/16 radii. Not borrowed: Linear's
   accent, type, or any asset. This is an approximation, not an official system.

   Radius rule (single scale): controls 8, panels 12, frames 16, status pills full.
   Status never relies on colour alone: every status carries an icon and a word.
   ========================================================================== */
