   Theme by setting the --bos-* custom properties (BosShell does this from
   its parameters; you can also override them in your own CSS).

/* ---- Hover trigger strip: DISABLED 2026-09-10 ----
 *
 * This was a transparent 48px strip covering the FULL HEIGHT of the left edge at z-index 9999,
 * shown whenever the rail was collapsed. Entering it slid the rail open.
 *
 * In this app the content area is somebody else's tool in an iframe, and tools put their own
 * navigation exactly where this strip was: reaching for VaultWarden's sidebar opened our rail over
 * it and pushed the page. Directus and Excalidraw have controls at that edge too, so it was one bug
 * with three victims.
 *
 * Neutralised here as well as unbound in bos-shell.js, so a stale copy of the markup cannot put an
 * invisible click-eater back over a customer-facing tool. The rail still opens: .bos-drawer-toggle
 * below is a visible tab at the left edge on desktop and it opens the rail on click.
 *
 * Kept as a rule rather than deleted with the element so that this explanation sits where the next
 * person looks, which is the CSS, not the git history.
