   TranXwatch-Solar Console — typefaces

   IBM Plex Sans + IBM Plex Mono, self-hosted.
   © 2019 IBM Corp. SIL Open Font License 1.1 — see /fonts/LICENSE.txt
   (the OFL requires the licence to travel with the font files).

   Self-hosted rather than CDN-linked on purpose:
     - helmet's default CSP already allows font-src 'self', so no policy change
     - no third-party request on every page load (no external dependency, no
       privacy leak, no failure mode when a site link is slow)
     - Lagos operators on poor connectivity get the real face, not a FOUT

   Latin subset only. Five files, ~106 KB total, cached indefinitely by the
   browser after first load.

   font-display: swap — text paints immediately in the fallback and swaps when
   Plex arrives. On a monitoring console, never hide the numbers waiting on a
   font.

/* Used for identifiers a person reads character-by-character and may need to
   transcribe: RFID tags, meter IDs, device IDs. A monospace face with a slashed
   zero removes 0/O and 1/l ambiguity — which matters when an operator is
   matching a tag against a physical label in the field. */
