/*
 * 热榜聚合 — /rebang/, other platforms' rankings, grouped 大陆 / 台港 / 海外.
 *
 * HAND-WRITTEN, NOT GENERATED. chrome.css, submit.css, fanqiang.css,
 * after-the-wall.css, home-skins.css, source-profile.css and wenku-skins.css
 * are built by scripts/build-*.sh and an edit to any of them is reverted by the
 * next build (scripts/check-builds-idempotent.sh exists because that happened
 * twice on 2026-08-30). This file is its own, loaded only on /rebang/.
 *
 * EXTENDS THE PAPER, DOES NOT RESTATE IT. Every colour is an existing token
 * (--ink, --ink-2, --rule, --rule-strong, --accent, --bg), so dark mode comes
 * free: theme-dark.css re-binds those names site-wide and this file inherits
 * the rebinding. The --mh-* family is FRONT-PAGE ONLY and must not appear here.
 * Fallbacks mirror chrome.css so a token-less context still renders.
 *
 * ------------------------------------------------------------------------
 * THE GROUPING IS THE LAYOUT, AND THAT IS THE WHOLE POINT OF THE PAGE
 * ------------------------------------------------------------------------
 * No other Chinese-language attention board carries non-mainland channels.
 * Ours does, and a reader has to SEE that without doing anything: 大陆, 台港
 * and 海外 stand side by side, as columns, at a glance. A tab strip or a
 * filter would hide the one thing this page has that tophub does not.
 *
 * So `.hotl-groups` is a grid whose column count comes from `data-n`, written
 * by the renderer as the number of groups that actually have panels today. An
 * empty group is never rendered, so the grid never carries a headed void — the
 * blank space the owner has objected to three times.
 *
 * THE ONE-GROUP CASE IS DIFFERENT ON PURPOSE. While only 大陆 has channels,
 * a single column of panels down the left of a 1080px page would be a third of
 * a page and two thirds of nothing. At data-n="1" the lone group spreads its
 * OWN panels across the width by multicol instead. Multicol rather than grid,
 * for the reason hot.css records: a grid with fixed rows leaves column two
 * empty whenever the content is short, multicol balances.
 *
 * PHONE TIER IS LAST IN THE FILE AND MUST STAY LAST — chrome.css, deep.css and
 * home-rescue.css guard theirs the same way. Append new rules ABOVE the banner.
