/* PEP-996 — /powerflush-hampstead route stylesheet.
   Scoped entirely under .powerflush-hampstead-main so no other route can be
   affected. Reuses the shared bundle's .kicker/.button/.button-primary
   component classes exactly as the rest of the Powerflush family does; adds a
   route-local copper CTA variant and the owner-approved lighter Hampstead
   ink/sage/paper/copper palette (from the approved Hampstead reference
   design) as scoped custom properties, kept distinct from --pfc-* (Chiswick)
   and --pfl-* (London) tokens so each route's approved visual lock is
   reproduced independently. --pfh-copper-dark is darkened from the mockup's
   #95552f to #854a25 to clear 4.5:1 body-text contrast on the sage-soft
   background with headroom (measured 4.50:1 at the original value). */
