/* ════════════════════════════════════════════════════════════════════════
   JustSign — global design system
   Tokens + base styles per docs/style_guide.md.

   Guidelines for editors:
   ─ Tokens are the contract. Color/spacing/font values everywhere go
     through var(--*). Don't hard-code hex/px in templates.
   ─ Add to THIS file when a class is used (or could naturally be used) on
     more than one page. Genuinely page-specific styles stay inline in the
     template that owns them so they're co-located with their JS.
   ─ Inline style="…" attributes are fine for 1–2 tactical properties.
     If you find yourself writing the same 3+ declarations in 3+ places,
     promote them to a class here.
   ─ Page-specific CSS already lives inline in:
       templates/forms/edit.html  — field editor (sticky toolbar, field-row,
                                    signers panel, question modal, PDF overlays)
       templates/s.html           — public signing page (field overlays,
                                    sign modal)
       templates/forms/view.html  — Overview tab grid + token chips
       templates/forms/new.html   — upload drop-zone
