/**
 * ReSense Design System — component styles (draft, proposal stage)
 * ------------------------------------------------------------------
 * Styles the shared reference markup (reference.html). Blade partials
 * and Vue SFC templates copy that markup verbatim and link this file —
 * the classes are the contract, this CSS is the single implementation.
 *
 * Rules: consume ONLY --rs-color-{role} + structure tokens from
 * tokens.css. No palette steps, no raw color values.
 * Naming: .rs-{block}, .rs-{block}__{element}, .rs-{block}--{variant}.
