# NeuraAI — division theme layer
#
# Loaded AFTER assets/css/main.css. It does three things and no more:
#   1. re-points the inherited template's accent token to the NeuraAI
#      signal colour (warm orange) defined in the group design system;
#   2. styles the NEURA / AI brand lockup;
#   3. styles the group bar and footer group strip that connect this
#      division back to Neura Digital.
#
# The inherited stylesheet uses var(--accent-color) in 334 places, so the
# division signal colour is genuinely a token swap rather than a re-skin.
# Changing the four values in the ":root" block below re-themes the whole
# division; that is the mechanism NeuraSec / Enterprise / MSP will reuse.
