/* Entry 012 — The Tab
   Series: The Attention Ledger.
   Scene art direction: a quiet bar after close. One cool pendant glow from
   upper-center over an empty counter; deep teal-blue night. Three layers:
   backdrop atmosphere → a faint counter sheen → the frosted-glass tab, the only
   sharp thing in the room. One accent: warm amber, reserved for the running total.
   Design focus: a single component, given the whole frame and plenty of air. */
