   AMP Installations Ltd — "The Wall"
   --------------------------------------------------------------------------
   base.css owns the reset, shell, header/nav mechanics, buttons, footer
   skeleton, reveals, preloader shell and the hero headline contract.
   This file supplies the palette, the wall elevation, the installation
   schedule and every section's own rhythm.

   GROUND: solid #ffffff. No bone, no cream, no warm off-white anywhere.
   Rhythm: white (hero + 01) → ink (02) → white (03) → ink (04) →
           white (05, pale table) → blue (06) → white (07) → ink (contact) → ink footer.
