/* ZSX landing/login redesign (#359, owner-approved artboard
   ui/v2/screens/landing.html): apple.com STRUCTURE (frosted slim nav,
   quiet oversized hero, whitespace rhythm) in the app's Frost White
   glass palette. ADDITIVE layer over auth.css — every auth element id
   and the JS contract are untouched; this file only reskins/relayouts.
   Scoped under body.landing-page so auth.css keeps serving any legacy
   embed of the auth card. */
