/* Portal skin: a dark content aggregator, laid out like a live-streaming
 * front page.
 *
 * Everything here is scoped to `body.portal`, so the room page keeps the
 * editorial styling from app.css. app.css still supplies the reset, the font
 * faces and the type scale; this file replaces the palette, the page frame and
 * every component the portal uses.
 *
 * Geometry (measured at a 1440 viewport, 24px gutters):
 *   header      60px fixed, blurs the content behind it
 *   sub-nav     capsule row, 32px tall, wraps horizontally
 *   banner      200px, rounded 12px, dots bottom-right
 *   main        55 / 45 split: focus stage left, 2-col cards + follow rail right
 *   feed        auto-fill cards, 16:9 covers, infinite downward
