/**
 * Secondary sidebar for the prosumer Apps area (PAP-10856; three-door IA
 * PAP-13254 / U3).
 *
 *   ← Back · APPS: Browse / Connections / Review (n)
 *   DEVELOPER: Gateways / Profiles / Rules / Health / Activity
 *
 * The three consumer doors are peers: "Browse" (the store — discover + add),
 * "Connections" (your connected tools + health), and "Review" (PAP-12371,
 * Finding B — decisions waiting on your OK, with a live pending count).
 * "Needs attention" is no longer a door: health/error triage folds into
 * Connections as a status filter + banner, so approvals are never buried
 * behind an error label. The Developer section was folded in from the retired
 * ToolsSidebar (PAP-10915) so the whole Apps area shares one sidebar; a
 * one-line caption frames who it's for (Finding A). "Run your own" and "Paste a
 * config" moved out of the sidebar into rows on the Connect-an-app page
 * (PAP-10922).
