   AIRO — "The Chamber"
   --------------------------------------------------------------------------
   base.css owns the reset, wrap, sections, header/nav/mega mechanics, buttons,
   forms, footer skeleton, reveals, preloader shell and the hero contract.
   This file supplies the palette, the chamber drawing and the report sections.

   Rhythm: white (hero) → ink (1.0) → white (2.0) → blue (3.0/4.0) →
           ink (5.0) → white (6.0) → blue (contact) → ink (footer)
