/* ==========================================================================
   e-invoice-generator.css — public generator workspace (G4.1A structure,
   G4.1B consolidated visual system).

   ONE design system, scoped to .gen-page:
   - five text roles:      --t-title / --t-section / --t-group / --t-body / --t-meta
   - three font weights:   400 / 600 / 700 (no others anywhere in this file)
   - one spacing scale:    --s1..--s8 = 4 8 12 16 24 32 48 64 px
   - one standard border:  1px (selected: 2px)
   - one standard radius:  8px (document preview: 12px; circular indicators: 50%)
   - one shadow:           the rendered PDF page only
   - card depth:           workspace surface + exactly one nested level (gallery
                           tiles, drop zone, dialog)
   - control heights:      40px standard, 48px primary, 32px toolbar icons
