================================================================================

  [HOOD STRIKER LOOP] ===> Drops into Latch Assembly bolted to Radiator Support:

   1. PRIMARY LATCH PAWL (Cable-operated from cabin lever):
      Holds hood flush & sealed against rubber weatherstripping.
   2. SECONDARY SAFETY CATCH HOOK (Spring-loaded manual lever under hood lip):
      Meant to catch the hood if Primary Latch pops open.
      * FAILURE MODE: Winter road salt & grime corrode the pivot pin of the
        Secondary Safety Hook -> When you pull the cabin release lever, BOTH
        hooks stay stuck in the "OPEN" position -> Next time you close the hood,
        the Secondary Hook never springs back over the striker bar.
