/*
 * App pages.
 *
 * The palette is the parent site's — dark ground, gold rule, warm text — so a
 * subpage is recognisably part of 45to23 rather than a different site that
 * happens to be linked. Each app then brings one colour of its own, `--c`, and
 * it is used sparingly: a rule under the icon, the button, the glow behind the
 * hero. Enough that Tripmi and GlowMaxing do not feel interchangeable; not so
 * much that the pages stop matching each other.
