/*
 * gonglogic.com — the front page (HomePageController), rewritten 2026-10-25.
 *
 * A plain file like the library's, studio's and audio site's: the page's look changes
 * without rebuilding the shared theme. Everything is under `.home`, the page's own
 * wrapper, so nothing here can reach another page.
 *
 * ── HOW IT WINS AGAINST THE THEME
 *
 * This file is printed BEFORE main.css (controller requirements come first), so a tie
 * goes to the theme. The theme styles bare elements (h1, p, a, a:hover), so element
 * resets are `.home :where(h1)` (0,1,0, beating the theme's 0,0,1) and every component
 * is `.home .x` (0,2,0, beating `a:hover`'s 0,1,1).
 *
 * ── HOVER CHANGES PAINT ONLY
 *
 * A :hover rule here may change colour, background, border colour and shadow, never
 * size, padding, border width or weight: a control that grows under the pointer moves
 * the thing beside it. `check:read-hover` measures it.
 *
 * ── NO DARK MODE, ON PURPOSE
 *
 * The main site's theme has none (its header and footer are light paper and dark ink
 * whatever the system asks for), so a dark front page would sit between a light header
 * and every light page it links to on gonglogic.com. The Library has a real one.
