The panel referenced its own token names (--bg2/--tx/--tx-dim/--ac/--card)
that don't exist in the app, so it always fell back to hardcoded dark
values — mismatched on the light and Night-orange/green themes. Alias
those tokens to the app's theme tokens (--bg / --ink / --muted / --accent
/ --bg-soft-2) at the panel root, fix the active white-overlay fills that
vanished on light backgrounds (rows, input, toast), map the accept action
to --online, and soften the shadows. The panel now follows the active
theme; the game-piece colours (X/O, chess, Connect-4) stay as-is.
