   Procapita Research Hub — application stylesheet.

   Layer order matters and mirrors the design prototypes exactly:
     tokens/fonts → colors → typography → spacing → radius → shadows
     → fig-tokens → base → (this file)

   fig-tokens.css deliberately re-points --text-primary at pure black, which is
   what the prototypes render. Do not "fix" it here — it is the intended cascade.
