   Maxer Photonics — Typography
   Manrope (display) carries the brand's confident, geometric voice.
   Inter (body) stays neutral and highly legible for technical reading.
   IBM Plex Mono (utility) marks anything instrument-readout-like: eyebrows,
   figures, units, product codes — a deliberate nod to spec-sheet/oscilloscope
   readouts rather than a decorative monospace.
