   page.css - v16 content surfaces (tier-1 pages + the home scroll sections).
   Same design language as app.css: Barlow Condensed display, Hanken Grotesk body,
   JetBrains Mono micro, dark pit-lane plates, gold hairlines. Type sizes come
   from the type-v16.css ladder (--f-*), so this file sets no px sizes except
   the ones type-v16 does not cover.
