/* ═════════════════════════════════════════════════════════════════════════════
   Vault — stylesheet
   Inter is loaded once, via <link> in index.html.

   The system, so new UI doesn't have to invent its own:

     TOKENS      :root holds the only colours, radii, shadows and control
                 metrics. Never hardcode a radius or a control height.
     SHAPE       Clickable things and surfaces are squircles using the --r-*
                 scale. Passive indicators (badges, chips, dots, spinners,
                 progress, toasts) are fully round. That's the whole rule.
     BUTTONS     .btn is the only button. Variants: .btn-primary,
                 .btn-danger, .btn-danger-solid, .btn-ghost. Modifiers:
                 .icon (square), .sm, .btn-block, .active, [disabled].
     MENUS       .menu + .menu-item + .menu-label + .menu-sep is the only
                 popover. openMenu() in main.js places it.
     TOOLBAR     .toolbar > .tb-rail > .tb-group. One non-wrapping row that
                 scrolls; dividers and empty groups handle themselves.
     MODALS      .modal-content (+ .modal-sm/.modal-md/.modal-lg),
                 .settings-section for grouping, .modal-buttons for the footer.

   Adding a toolbar button: put a <button class="btn icon"> in the right
   .tb-group in index.html. No CSS, no media query, no JS layout work.
