/* Docs-style shell for /academy pages — injected by tools/academy_shell.py.
 *
 * The problem this solves is not decoration. Search and AI assistants deep-link
 * readers straight into one article, and until now that one article was the whole
 * site as far as that reader was concerned: no way to see that sixteen others
 * exist or how they relate. The left rail makes the archive reachable from any
 * page, the right rail makes a long article skimmable.
 *
 * Colours come from the :root block already inlined in every academy page, so
 * this file adds layout only and stays in sync with the theme automatically.
