   Section 22 — Theme toggle (segmented control)

   Changes from previous version:
   - No more `margin-left: 28px` — the toggle is now a real
     <li> inside the primary-nav <ul>, so it inherits the 28px
     gap automatically.
   - Hide labels at ALL viewport sizes; rely on icons + tooltips.
     Saves ~120px of horizontal real estate and lines up with
     the masthead "system reading" aesthetic.
   - Slightly tighter padding (5px 9px) so the pill height
     matches the nav-link baseline (~28px tall).
   - Add `.theme-toggle-slot` rule to ensure the wrapper <li>
     doesn't pick up any inherited menu-item styling.
