/*
 * Senior Word Search — front-end styles (v1.1 redesign).
 *
 * Design direction — "the puzzle-book page": a warm paper surface with deep
 * slate ink and a friendly serif display face, the grid presented as a raised
 * puzzle board, amber for in-progress selection and deep teal for found words.
 * Found words also get a strikethrough and a check, so state is never colour
 * alone. The signature element is the oversized Easy/Medium/Hard switcher with
 * ● / ●● / ●●● dots — the dot count itself encodes the difficulty.
 *
 * Accessibility floor: 48px+ targets, visible focus rings, keyboard operable,
 * reduced motion respected, responsive to small screens, print-friendly.
 *
 * Colours and base size are injected as CSS custom properties on .sws-game.
