/* FOREVER:NEON — OP-03 HIDDEN CARRIER
   KFI HCM-88 — Hidden Carrier Monitor / RF Anomaly Tracer

   Built on the shared Book 1 instrument kit (book1-instruments.css /
   .js) which this file must load AFTER. This is Sid's earliest known
   build -- six weeks before the WR-6 (Operation 08) -- assembled in
   his father's repair shop out of whatever the parts bin had. It
   should read as the least mature, most visibly improvised instrument
   in the KFI family: real wideband-receiver logic, patched together,
   not yet the standardized shop it becomes by chapter 8.

   Layout mirrors the WR-6 pattern established for SIGILTRY (chassis /
   nameplate / annunciator strip / content bays / lower furniture /
   basebar) without reusing its wr6-* classes directly -- this is a
   different device in the same universe, so it gets its own hcm-*
   namespace layered on the shared fn-* primitives. */
