   RFID FIXED ASSET MANAGEMENT — DESIGN SYSTEM
   Built on top of Bootstrap 5 utilities/grid; visual language is custom.

   Design language: "Live Read" — every RFID tag read is a small radio
   pulse. That pulse (concentric rings expanding from a point) is the
   signature motif used in the hero visual, section eyebrows and
   loading/status states, instead of generic accent lines or numbered
   circles. Palette follows the brief: white / dark blue / grey / black.
