/* map-controls.css — the styles of map-controls.js (@strata/map-controls), and nothing else.
 *
 * Everything is scoped under the root class `.smc`, which mountMapControls() puts on its container.
 * Colours come from CSS custom properties. Each --smc-* token falls back to the house token of the
 * same role (--bg, --panel, --fg, --muted, --border, --accent, --shadow, --motion), then to a
 * built-in light/dark default (the module sets data-smc-mode on the root from theme.mode).
 * An app with other token names maps them in, after this file:
 *     .smc{ --smc-bg:var(--my-surface); --smc-accent:var(--my-brand); … }
 * The container must be a positioned box (position:relative/absolute) — the cluster and the drawer
 * are absolutely positioned inside it.
