/* ===================================================================
   electricalswitchgearremoval.com — "Cubicle & Bus"
   See ../ideas.md. Replication of the Texas site's orange-on-charcoal
   livery and hero/form layout, differentiated by typeface pairing,
   a deeper orange + bus-copper secondary, and the cell-gap divider motif.

   HARD RULES reflected here:
     - dark theme site-wide; safety orange signature
     - quote form sits INSIDE the hero, beside the copy, orange top border
     - ONE round orange floating call button, bottom right
     - square corners (max 2px) except the call button
     - zero JavaScript: FAQ is details/summary
