/* ==========================================================================
   Trips — design system (SPEC §10). A calm, legible transit board.
   Public Sans for UI; IBM Plex Mono for travel data (times, PNRs, berths,
   coordinates) — anything read aloud on a platform at 01:00 gets .mono.

   COMPONENT CLASSES — views should use these, not invent new ones.

   Utilities   .mono  .muted  .faint  .small  .label (mono caps caption)
               .stack (vertical rhythm)  .cluster (wrapping row)  .spacer
               [hidden] always hides.
   Layout      .view (a mounted view's root)  .section-title (h2/h3 with rule)
               .group-heading (sticky date heading inside a list)
               .empty (centred empty / loading state)  .footer-note (build no.)
   Itinerary   li.row.leg-row (.past = departed, dimmed) > .leg-time (.leg-clock .leg-zone)
               + .row-main (.leg-tags .leg-home)
   Board       .board  > .board-label  .board-row  .board-time  .board-zone
               .board-route  .board-countdown  .board-meta  .board-empty
               (always dark, both themes — it is the departure board)
   Cards/lists .card (.card.flush = no padding, for lists)
               ul.list > li.row  > .row-main (.row-title .row-sub)  .row-end
               li.row.done (struck-through)  li.row.tappable (button-like)
               .row-title.cluster (title text + a .tag that wraps cleanly)
   Badges      .badge + .soon (amber, ≤3 days) | .overdue (red) | .later (neutral)
               .tag (outlined mono tag on legs)
   Chips       .chips (horizontal scroller) > button.chip[aria-pressed="true"]
   Segmented   .segmented > button[aria-pressed="true"]
   Buttons     .btn  .btn.primary  .btn.danger  .btn.ghost  .btn.small  .btn.block
               .icon-btn (44px square, put an <svg> or glyph inside)
               .fab (round "+" button above the tab bar)
   Forms       form.form > label.field (.field-label, control, .field-hint)
               .field-row (two fields side by side)  label.check (checkbox row)
               .form-error  .form-warn  .form-actions
               (dom.js field()/input()/select()/textarea() produce these)
   Sheets      dialog.sheet > .sheet-head (.sheet-title) + .sheet-body;
               .sheet-actions for button rows (dom.js openSheet/confirmSheet)
   Banners     .banners > .banner + .danger | .warn | .info, .banner-action
   Readout     .readout (huge copyable mono text, e.g. "52.3676, 4.9041")
   Feedback    .toast-region > .toast   .update-bar   .ptr / .ptr-button
   Theme       html[data-theme="light"|"dark"] overrides prefers-color-scheme.
