// Plugins page (`#plugins`) — the admin board of every registered plugin,
// and the single plugin management surface (the old per-user `#plugins`
// page is gone: a plugin with per-user settings — Telegram's pairing,
// Honcho's opt-in — hosts them in its own sidebar page via `web_pages()`).
//
// One card per plugin: an enable/disable toggle, a health dot (green =
// enabled, running and fully configured; red = enabled but broken; grey =
// off) and a Configure button opening the plugin's own detail page
// (`#plugin-detail?id=…`). Instance config and user-access grants live on the
// detail page, not here — the catalog stays a quick status board.
//
// Styling reuses the connectors card grid (`web/css/connectors.css`).
