/**
 * pie-menu.css — Senastra Pie Menu Styles (v2 — Blender-inspired)
 *
 * Redesigned for PieSystem + PieRenderer architecture.
 * Key changes from v1:
 *   - Items positioned via transform (GPU-accelerated)
 *   - Direction-aware text alignment (Blender's factor[] logic)
 *   - prefers-reduced-motion respected
 *   - Lighter DOM: no shortcut modal, no context menu (host app responsibility)
 *
 * Required token files:
 *   tokens/design-tokens.css
 *   tokens/design-tokens-extended.css
 *   themes/themes.css
