/*
 * Cogis page styling. Self-hosted, no fonts fetched, no third-party origin —
 * `style-src 'self' 'unsafe-inline'` (§3.7) allows an inline style, but nothing
 * here needs one, so the page ships zero inline CSS.
 *
 * Group boxes reserve their height up front (`--group-min-h`) so arriving
 * chunks swap content inside an already-sized box instead of moving the page
 * under the reader (§6 M8b AC #8).
