/* ─────────────────────────────────────────────────────────────────────────────
   LSC Billing: base stylesheet.

   Began as a port of the Electron app's <style> block. The Electron app is
   retired, and so is the Desktop Preservation Law that froze this file (U16,
   .design/ui-clarity/). Edit these rules directly; don't add override layers.

   Every value comes from tokens.css, which loads first: the --color-*,
   --space-*, --font-* names for anything new, and the legacy aliases (--bg,
   --surface, --border, --text, --muted, --accent…) that the older rules here
   and in every screen file still read. No raw hex, and no font names.
   ───────────────────────────────────────────────────────────────────────────── */

@font-face blobs became real files in ../fonts/ (below);
     • -webkit-app-region declarations were dropped (Electron-only).

   The Desktop Preservation Law applies: do not edit rules in this file. The
   >=1100px layout must stay pixel-identical to the desktop app. Responsive and
   accessibility work is additive, in files appended after this one.

/* ── Buttons (ui-clarity task 2, U4, U17) ─────────────────────────────────────
   Four kinds, two sizes, sentence case. Plain .btn is the secondary button.
     .btn-primary  terracotta, the only caps button, one per view or row.
                   .btn-accent is the same button under its old name.
     .btn-quiet    text only: Cancel, a row's secondary actions.
     .btn-ghost    quiet with a hairline ring, where a bare word would read as
                   text rather than a control (rows of document actions).
     .btn-danger   red text and ring; destructive, and asks first.
     .btn-sm       --control-h-sm. .btn-xs is the same size under its old name.
   .btn-secondary is accepted as a name for plain .btn and needs no rule.
   Below 768px both heights are --touch-min (tokens.css). Edges are inset
   box-shadows, not borders, so every kind is the same size and a ring never
   shifts a label. The focus ring (--shadow-focus) replaces them while focused. */

/* ── Panels (ui-clarity task 2, U2) ───────────────────────────────────────────
   A section of a screen: one layer up from the page, its own head bar, rows
   inside separated by hairlines only. The head holds a title, an optional
   count or subtotal, and at most one action. Panels carry no margin: the
   container that stacks them sets the gap (--panel-gap).

     <section class="panel" aria-labelledby="x-title">
       <div class="panel-head">
         <h2 class="panel-title" id="x-title">Documents<span class="panel-count">3</span></h2>
         <button class="btn btn-quiet btn-sm">⋯</button>
       </div>
       <div class="panel-body">…</div>
       <div class="panel-foot">…</div>
     </section>

   Collapsible: the title holds a real button, and the summary sits inside it,
   so a closed panel still says what it holds and the whole bar is the target.
   js/panel.js turns it; the body is [hidden], so its inputs stay in the DOM.

       <h2 class="panel-title" id="x-title">
         <button type="button" class="panel-toggle" aria-expanded="true" aria-controls="x-body">
           <span class="panel-chev" aria-hidden="true"></span>
           <span class="panel-name">Services</span>
