/* Firefly site chrome — shared by index.html and sedgepatent.html.
   Page-specific layout stays in each page. Do not duplicate these rules.

   Drift reconciled while extracting (same-named rules that differed):
   - .agree checkbox: homepage custom control (accent #6b6b70, appearance:none,
     checked checkmark). SEDGE page had a native checkbox with accent #2cdc9e.
   - Gradient animation: keep -webkit- prefixes (homepage had them; SEDGE did not).
   - Accessibility widget: homepage set host opacity .8; SEDGE left it at 1.
     Shared: opacity .8 and --acc-widget-z-index: 200 (widget default was 100000).
   - .acsb-trigger was a dead selector (wrong widget). Real host is #acc-widget-host.
   Unused homepage leftovers on the SEDGE page (hero-content, full-bleed-img,
   sedge-section, device-visual) were not carried into this file.
