/* =====================================================================
 * rw-practice.css — SAT R&W 2-column practice (Bluebook-style).
 *
 * Fine-tuned 2026-05-19 against actual Bluebook screenshot:
 *   - Header BG white (not gray)
 *   - Right-side tools: Highlights & Notes + More (stacked icon/label)
 *   - Banner = dark navy
 *   - Passage panel = white (same as question panel)
 *   - Vertical splitter = dashed line with a small white pill containing ⟷
 *   - Question bar: black "n" badge + Mark for Review + ABC annotation button,
 *     dashed bottom border
 *   - Choices: thin-border boxes with circle letter on the left
 *   - Footer Next/Submit = BLUE pill (Bluebook R&W uses blue, not Math-yellow)
 *
 * Overrides dsat-style.css in places where Bluebook R&W diverges from
 * Bluebook Math (e.g. header BG, footer button color).
