/* ============================================================
   Operations Hub website (ADR-0003), second design, 2026-10-27.
   Sam: "the same sleek design as the Tesla website". The site now wears
   the app's own look (hub.css, the minimal look): Carbon, Pearl, one red
   action, one typeface. The home page is a stack of full-screen pictures
   of the app, a title and one line over each, two buttons under them.
   Surfaces step up in shade instead of borders and shadows. Sentence case
   everywhere. The only things that move: each picture drifts slowly while
   it is on screen, and a section's words rise once as it arrives.
   ============================================================ */
