/* nes20-extension.css: styles for R-Z5.2.X-NES20-HEADER-2026-05-16.
 *
 * Adds NES 2.0 toggle-bar + warn-banner styles for the hex viewer
 * embedded in courses/spk-101/week-2-rom-bytes.md. Scoped under
 * .va-cog-hex-* tokens so it composes cleanly with the Z5.2 portal.css
 * surface without touching that file (per acceptance criterion 8 of
 * the R-Z5.2.X brief).
 *
 * Per Jon's standing directive (highest quality), the toggle buttons:
 *   - reuse the same amber-on-dark palette as the bookmark-bar buttons
 *   - meet the 44x44 tap-target floor (primary nav affordance) per
 *     WCAG 2.5.5; mobile-friendly out of the box
 *   - carry a clear active state so students see which ROM is loaded
 *   - degrade to a stacked layout on narrow viewports
