  /* Always reserve scrollbar space — prevents 8px horizontal layout
     shift ("jerk") between pages whose content does/doesn't overflow
     the viewport. Operator on 2026-05-11 reported visible jerks when
     navigating between /connect (taller, scrollbar appears) and
     /leaderboard (shorter, no scrollbar) — measured via CDP as
     main.width changing 1532 ↔ 1540 across the swap.

     Why both rules together:
       - ``overflow-y: scroll`` forces a scrollbar slot to always
         exist on the html root, even when content doesn't overflow.
         This is the universal cross-browser fix; works in every
         engine. Without it, the html element's overflow stays
         ``visible`` (the default) which gives variable-width
         scrollbars on pages that overflow and zero space on pages
         that don't.
       - ``scrollbar-gutter: stable`` is the modern spec replacement
         (Chrome/Edge 94+, Safari 18.2+, Firefox 97+). Once the
         baseline rises we can drop ``overflow-y: scroll`` for it.
         Until then both coexist safely — when scrollbar-gutter is
         honored, overflow-y:scroll just contributes the same gutter
         (no extra). */

   Cross-document View Transitions
   ──────────────────────────────────────────────────────────────────
   Enabled in the browser via <meta name="view-transition"
   content="same-origin"> (added by instant-nav.js). For each element
   we want to track across page navigations we set a
   ``view-transition-name``. The browser then knows "this element on
   page A is the same logical element as the one with the matching
   name on page B" and:
     - If they're at the same position with the same dimensions
       (typical for the sidebar, which is fixed-positioned and
       identical across every authed page) → NO transition is
       rendered for that element. From the user's perspective it
       "stays put" across the navigation.
     - The rest of the page (with no name OR the default
       ``::view-transition-old(root)`` / ``::view-transition-new(root)``)
       cross-fades.
   The result: clicking a sidebar link feels like a true SPA — sidebar
   doesn't reload, content fades to the new page. Chrome/Edge 126+,
   Safari 18.2+; older browsers fall back to a plain navigation (still
   correct, just no cross-fade). */

/* ==========================================================================
   NEW DESIGN STRUCTURAL CLASSES (Phase R2)
   ==========================================================================
   These are classes the new Claude Design uses that we don't have yet.
   Adding them alongside our existing classes (.app-shell / .app-main /
   .app-header / .app-content) so pages can opt-in incrementally during
   R3 without breaking pages that still use the old names.

   The visual style here matches the design bundle's app.css exactly,
   re-tokenised through our :root variables so light/dark mode works
   identically with our existing [data-theme] mechanism.
