   Muhammad Abdullah — v3c
   Layout and visual language modelled closely on frontal.so:
   dark-dominant grounds, one hot orange accent, [ mono tags ]
   in brackets, flat hairline panels with title bars, dashed
   connectors, huge numerals in the proof row.

   Content, copy and branding are entirely his own.
   No backdrop-filter, no JS animation loop, no dependencies.
