   Taprun site stylesheet — single source of truth for every page except the
   homepage hero system (docs/index.html keeps its own landing-page styles).

   Before this file existed, ~45 pages each carried their own inline copy of
   these rules, most with hardcoded hex values. Change colors HERE, not there.

   Design system: near-black surfaces, lime signal, Space Grotesk + JetBrains
   Mono. Matches the homepage so there is no jump between landing and content.
