   Tool-Detail-Page · shared stylesheet

   Per-page only sets the tool-specific glow as :root override:

     :root {
       --tool-glow:    rgba(R,G,B,0.34);   // hero outer-left wash
       --tool-glow-2:  rgba(R,G,B,0.20);   // hero outer-right wash

       --tool-accent-soft: rgba(R,G,B,0.10);
     }

   Optional: --hero-bg gradient may be overridden for tools
   that benefit from a chromatic shift (e.g. Pia red-tinted).
