/* ============================================================
   .s-feedback-ladder — Act 5 · Fast feedback loops.
   "An agent is only as fast as the feedback loop."

   Two-step reveal:
     step 0  THE PROBLEM. WebLogic + EAR, 2010. A frozen startup
             log and a stopwatch parked at ~30 min, centered.
             Speaker delivers the analogy: the agent lives in this
             same loop.
     step 1  THE ANSWER. The WebLogic card demotes to a compact
             "legacy" strip pinned to the top of the stage; below
             it, a 4-rung Java tooling ladder cascades in — fastest
             at top, slowest at bottom — with real timing badges
             keyed to a green→amber→red speed rail.

   Visual idiom: shares the dark-navy terminal-card chrome with
   .s-blackbox and .s-specs-vs-tests so it reads as a sibling
   surface in the same Act V room.
