 * The one product's frame: the sidebar (six items), the top bar and the open item's tabs. One file, served by Snappy at /shell/shell.css
 * and linked by both apps: Snappy's pages (app/Shell.tsx) and the SOP pages under /procedures (their embedded mode), so
 * the two draw the same frame from the same rules. The markup is built from the same model (web/src/shell/navModel.ts,
 * GET /api/shell/nav). Tokens are its own (--shx-*), copied from .claude/skills/snappy-ui/tokens.css (Paper and Graphite), so
 * neither app's own variables can change how it looks. Neutral; purple only on count badges and the logo mark.
