/*
 * Puzz shared-shell — modal CSS for the completion/share modal and the
 * daily-start modal. Identical across Tangle, Escape, and Split
 * (copy-pasted, no build step yet — see types.md). Fully self-contained
 * (hardcoded colors) so it looks the same regardless of each game's own
 * theme. Pair with the canonical markup in completion-modal.html /
 * daily-modal.html and shared-shell.js's initCompletionModal /
 * initDailyStartModal.
