/* Orbace Sudoku — canonical givens-entry grid styling (js/orbace-givens-grid.js).
 * Class names unchanged from the original admin.html-only implementation
 * (.pz-grid/.pz-cell/.pz-numpad/.pz-key), moved here so both admin.html and
 * the public Puzzle Challenge page can load one stylesheet instead of
 * duplicating rules.
 *
 * Palette/type match the Puzzle Challenge design mockup exactly
 * (~/Downloads/puzzle-challenge-flow.html's SudokuGrid.dc.html artboard,
 * 2026-08-28) — the same editorial palette as the API spec doc: paper
 * #ece6d8, line-strong #c7bea6, ink #24271f, jade #3e6259 (given digits,
 * selected/checked states), seal #a23b2e (selected-cell highlight). Cell
 * borders are set inline per-cell by orbace-givens-grid.js (color AND
 * width, for the thick ink-colored 3x3 box boundaries vs. thin line-strong
 * regular grid lines) — this file only supplies the fallback/base look.
