/**
 * Manifold — primitive component styles.
 *
 * Range-input pseudo-elements (track + thumb) can't be expressed via React
 * inline styles, so the Slider and ControlAxis primitives rely on these
 * className hooks. The dynamic bits are passed as inline CSS custom properties:
 *   - Slider:      `--mf-pct`        (0..1 fill ratio for the track gradient)
 *   - ControlAxis: `--mf-axis-accent` (per-axis track/thumb accent colour)
 *
 * Import this once at the app root (it is re-exported as a side-effect from
 * `primitives/index.ts`, so importing the barrel is enough), or add it to your
 * global stylesheet manifest alongside the design tokens.
 */

/* ---- Slider (.mf-slider-input) ---- */
/* Base reset so the custom track/thumb styling applies even when a consumer
   doesn't set these inline (e.g. OutputControlRow's held slider). The colored
   fill tracks `--mf-pct` (0..1); it falls back to 0 if a consumer forgets it. */
