/* Plumb book — custom theme overrides.
 *
 * Sidebar chapter links: ensure a >= 24 px touch target per WCAG 2.5.8
 * (Target Size, Minimum). The default mdBook theme produces ~22 px tall
 * sidebar anchors on common viewports, which trips Plumb's own
 * `a11y/touch-target` rule (default `min_height_px = 24`) when the docs
 * site is self-linted. Bumping `min-height` plus padding/line-height
 * keeps the sidebar above the 24 px floor without disrupting layout.
