/**
 * Tarjoman — frontend language switcher.
 *
 * Isolation strategy:
 *  - Every rule is namespaced under `.cmc-ls` — nothing leaks in or out.
 *  - Theme-facing knobs are exposed as custom properties on `.cmc-ls`, so
 *    integrators can re-skin without overriding internals:
 *      --cmc-ls-gap, --cmc-ls-radius, --cmc-ls-accent, --cmc-ls-panel-bg,
 *      --cmc-ls-panel-border, --cmc-ls-shadow, --cmc-ls-flag-size.
 *  - Layout uses logical properties exclusively (margin-inline, padding-block,
 *    inset-inline-start) so LTR/RTL flip automatically; no [dir] hacks needed.
 *  - Specificity is kept low (single class selectors) so themes can override
 *    trivially while our resets win against aggressive theme ul/li styles via
 *    targeted !important ONLY on list normalization.
