/* agentscope.ca — purple and amber on paper.

   The palette is the product's own logo: disc #4a1258, arrow #f5ba32, ground
   #fefdfc. Same system as the LinkedIn kit in dk-agentscope-marketing, so the
   page and the company page read as one thing.

   Type is a system monospace stack rather than the kit's NerdMono. The kit
   renders to PNG where a 900 KB face costs nothing; a landing page is not the
   place to spend that, and the register survives the substitution. */
