/* ============================================================================
   F2 — Shared style tokens (lightweight foundation; NOT a redesign)
   ----------------------------------------------------------------------------
   Semantic CSS custom properties are the single source of truth for the
   parchment / classic theme. Every token maps 1:1 to a value the app already
   used, so adopting them is a pure refactor with ZERO visual change.

   How to use this foundation for NEW UI (existing UI migrates incrementally):
     - Colors:      --color-bg, --color-surface, --color-felt, --color-ink,
                    --color-ink-muted, --color-border, --color-accent,
                    --color-success, --color-danger-ink, --color-gold,
                    plus player + card-suit colors.
     - Typography:  --font-sans / --font-mono / --font-display; --text-* scale;
                    --text-base / --leading-base for body copy.
     - Spacing:     --space-1 .. --space-6 (a small 4px-based scale).
     - Radii:       --radius-sm / --radius / --radius-lg / --radius-pill.
     - Elevation:   --shadow / --shadow-modal / --shadow-selected.
   Component primitives built from these tokens live at the bottom of this file:
     .btn / .btn-primary, .input, .panel, .modal-overlay + .modal.
   They reproduce the current looks and are ready for new UI; existing elements
   keep their own classes for now (no rewiring = no regressions).

   Legacy short aliases (--bg, --ink, --btn, ...) are kept below so existing
   rules — and cardFace.css, which references --ink/--shadow/--card-red — keep
   resolving to identical values. Migrate refs to the semantic names over time.
