   Amperes — dark industrial theme overlay
   Loaded AFTER style.css. Used by the marketing pages (index, solutions,
   use-cases, integrations). Docs and pricing keep the light theme — they
   are reference pages, not poster pages.

   Design language: full-bleed hero sections with video, sparse uppercase
   typography, black background, white text. No cards. No accordions. No
   bullets in body copy. Every section is a poster.
