/*
 * Bats: Fact or Fiction — Widget Styles
 *
 * THEMING — Trail Conservancy brand palette
 * ------------------------------------------
 * Colors pulled directly from thetrailconservancy.org (ttc-child/style.css).
 *
 *   --primary-color   #fc5000 — their brand orange. Used as header bg, button borders,
 *                     and hover fills. Note: #fc5000 on white is 3.26:1 — passes for
 *                     large text (buttons, h1) but not body text. For any small orange
 *                     text on white, use --primary-dark instead.
 *   --primary-dark    #1d252b — their dark charcoal. Used for outlined button text and
 *                     focus rings. 12:1 contrast on white — WCAG AAA.
 *   --accent-color    Focus rings. Kept as charcoal to match their dark.
 *   --success-color   "Correct!" result header.
 *   --error-color     "Incorrect!" result header.
