/* WA Productions x Nado partner program
   Palette matched to wa-productions.com: near-black surface, white, single
   red accent. Sourced from the live site's stylesheet:
   - dark surface:  #1a1a1a (.contact-us.bg--dark, header dropdown bg)
   - body/heading ink on light bg: #181212 (body.wp-front)
   - accent (links, buttons, borders): #bc2c2c (.button--primary, a, h2 span)
   - light section bg: #f8f8f8 (.uk-navbar-container)
   On dark surfaces the accent's contrast against #1a1a1a is too low for
   text (~2.9:1), so dark-surface foregrounds use white/light gray instead,
   matching how wa-productions.com itself treats its own dark sections. */
