/* ==========================================================================
   Rivalry-Week CFB Fantasy — Design System
   ==========================================================================

   Design rationale:
   - Notre Dame navy (#0C2340) as the signature dark base — deep and
     authoritative, the color of the Golden Dome at dusk.
   - Notre Dame gold (#C99700) as the single accent — used sparingly for
     scores, highlights, and CTAs. Richer and more muted than generic amber.
   - Warm white (#F0EEE9) for primary text — slightly cream, not clinical.
   - JetBrains Mono for all stat numbers — monospaced so columns align
     perfectly without a table layout hack.
   - Bebas Neue for display headings only — punchy but used with restraint.

/* ── Position chip (PASS / RUSH / DEF) ──────────────────────────────────────
   The single position chip for the whole app. Exactly two states:

     .pos-chip                 ACTIVE   — solid position fill, white text
     .pos-chip.is-inactive     INACTIVE — transparent, position-coloured text

   The per-position colour is carried in `--chip`, so both states derive from
   one value and no site needs to name a hex again. A chip with no position
   modifier falls back to the neutral dim colour, which is what an ownership
   chip (a team abbreviation rather than a position) uses.

   Do not add a third variant or restyle this locally — every chip in the app
   is meant to be visually identical. Width is the one thing that flexes: the
   min-width holds a position label and longer labels grow into the max-width.
