/* ============================================================================
   TOUCH TABLETS (iPad et al. — ≥768px, so desktop Augen layout, but finger-driven)
   ----------------------------------------------------------------------------
   A tablet is ≥768px and gets the desktop layout, but it's driven by a finger, which
   needs a bigger target than a mouse pointer. `pointer: coarse` matches ONLY touch, so
   mouse-driven desktops (`pointer: fine`) stay pixel-identical — this honors the
   "≥768px unchanged" guardrail's INTENT (don't degrade the desktop) while meeting the
   44px HIG/WCAG 2.5.5 target floor and the 16px rule that stops iOS Safari zooming the
   page on input focus. Phones (≤767px) are the separate app shell and never match this.

   Placed at the END (after every base rule it overrides) on purpose: an @media rule has
   the same specificity as the bare selector, so the cascade falls to SOURCE ORDER — a
   block earlier than `.search-submit`'s base rule silently loses to it. Only persistent
   chrome is bumped (nav · search · header cluster); hit areas grow, glyphs/type do not.
   Verified by /device-lab on the iPad cells. ============================================ */

   MOBILE APP SHELL (phones ≤767px)
   ----------------------------------------------------------------------------
   Purely additive: ≥768px renders exactly as before. The desktop pill nav and the
   phone chrome are two control surfaces onto the SAME `data-tab` panels — nothing
   is forked. Tokens only (--brand is the electric blue; --accent is the mono ink),
   so both themes come for free.

   Non-obvious constraints baked in here:
   - env(safe-area-inset-*) only resolves because index.html sets viewport-fit=cover.
   - Inputs must stay ≥16px or iOS Safari zooms the page on focus and the fixed
     chrome drifts out of alignment.
   - Record tables become cards via td::before + data-label; app.js fills data-label
     from each table's <th> (labelTableCells), so no render function changes.
