 * Bevel foundation. Every component builds on these tokens and utilities;
 * component stylesheets only add their own palettes and shapes.
 *
 * Layers:
 *   1. Light     one source, above and slightly in front of the screen.
 *   2. Depth     named elevations built from the light: recessed, flush,
 *                raised, pressed, object.
 *   3. Material  a surface recipe (leather, plastic, metal) that reads
 *                --bevel-material and --bevel-material-edge.
 *   4. Motion    two curves, a spring, and durations named by purpose.
 *   5. Shape     radii, stitching, and the type scale for amounts.
