/* AMBIE brand stylesheet — extracted from site/index.html so all pages
 * (signup, account, pricing, docs) share the same look as the homepage.
 *
 * Palette:
 *   Background:     #0A0A0A near-black
 *   Surface:        #111111 card / panel
 *   Surface light:  #151515 nav / footer
 *   Accent purple:  #8B5CF6
 *   Accent blue:    #3B82F6
 *   Text primary:   #FAFAFA
 *   Text muted:     rgba(255,255,255,0.7)
 *   Text subtle:    rgba(255,255,255,0.5)
 *
 * Tailwind CDN is still loaded on each page; this file is the BRAND layer
 * on top of that — gradients, glow, animations, glass surfaces.
