/*
 * Etechflow_OptionsPlugin — theme-adaptive option styling.
 *
 * Every colour here is a CSS custom property that efopt-theme-adopt.js fills in
 * at runtime from the LIVE theme (Luma / Adobe Commerce / Hyvä / custom). The
 * values below are only fallbacks used for the split-second before the JS runs,
 * or if colour detection finds nothing — so the UI is never unstyled or broken.
 *
 * Two layers:
 *   .efopt-choice            → always applied when "Adopt theme colours" is on
 *                              (accent on the radio/checkbox, selected emphasis)
 *   .efopt-card              → added on top when "Themed option cards" is on
 *                              (the bordered card layout)
