   FORGE left rail — DanielLab-style flow & placement, FORGE skin.
   Loaded ONLY on logged-in dashboard pages that mount
   <aside id="forge-nav" class="forge-rail">. Mirrors DL's left-nav
   structure + responsive collapse; keeps FORGE's dark identity
   (no color/font changes, no shadows — forge stays flat).
