   IQ TESTER PRO - design system "INSTRUMENT"
   ---------------------------------------------------------------------------
   Personality: a measuring instrument, not a marketing page. Hairline rules
   instead of drop shadows, a mono face for every number and micro-label,
   numbered sections, tight vertical rhythm, one accent used sparingly.
   Type: Space Grotesk (display) - Inter (text) - IBM Plex Mono (data)

   COLOUR: sampled from images/logo.png — a black wordmark beside a brain
   built from mint/aqua links, deeper teal nodes and pale-yellow highlights.
     logo mint  #A8E4D8   logo teal #66B4AE
     logo yellow #F6F0A2  wordmark  #000000
   The teal and yellow straight off the mark are too light to carry text, so
   --accent / --signal are darkened derivatives of them; the raw logo values
   live on in --accent-2, --accent-soft and --signal-soft.
