/* brand.css — Simple Context Memory */
/* Visual redesign: memory-themed palette, pink + teal, warm charcoal */
/* Mood: arctic.css tokens extended — grid killed, memory aesthetic applied */

/* Vocabulary:
   Primary:    Memory rose-pink  (#E879A8) — warm, neural, associative
   Secondary:  Synaptic teal     (#2DD4BF) — precision, recall, the other half
   Background: Warm charcoal     — no blue undertone
   Grid:       Killed
   Brain:      Faded silhouette in hero — 6.5% opacity, mask-faded at edges
   Memory bg:  Radial neural-glow on dark sections; synaptic dot scatter on hooks
   Shape:      Sharp — this is still a systems tool
