   Global: hide icons inside text buttons (designer rule)
   Icons are only appropriate in nav, cards, sections,
   and dedicated icon-only buttons.

   Responsive text-button icon rule:
   - Text buttons (.btn) hide their leading icon on
     wide screens (≥768px) so the action label leads.
   - Icon reappears below 768px when label may wrap or
     get truncated, giving users a recognisable glyph.
   - Opt-out: add .icon-keep on the <svg> to always show.
   - Icon-only buttons (.btn-icon-circle, .btn-icon-only,
     .nav-link, .ct-tab/.tab-item, etc.) are unaffected.
