/* Sriracha Court — design tokens + components, adapted from the Claude "Modernist"
   design export (see ../README.md). Sharp corners, thick hairline borders —
   that structural language stays; palette below is the warm/teal revision
   picked from the font+color comparison, replacing the original cool-grey/red.
   --color-accent is the BRAND color (buttons, links, active states).
   --color-alert is a SEPARATE, deliberately-not-brand color reserved for
   overdue bills / validation errors, so urgency never blends into branding. */
