/* ==========================================================================
   Rone Arena: "field manual" design system
   --------------------------------------------------------------------------
   The API is presented like a printed reference: black ink on paper, ruled
   lines instead of boxes, condensed heavy headings, monospace data, and a
   single highlighter colour used the way a highlighter pen is used (behind
   key marks, never as text colour).

   Rules this file enforces (from the anti-"AI slop" research):
   - no gradients-as-decoration, glows, blur, or decorative motion
   - no cards-in-cards; sections are separated by rules, not shadows
   - one accent, used sparingly; data colours carry meaning only
   - one border OR one shadow per surface, never both
   - body text 16px, line length capped near 70ch
   ========================================================================== */
