/*
 * NeuroX New Jersey public site.
 *
 * Ported from Athena's approved prototype (2026-10-20, artifact version 6).
 * Layout: a bright front door. Hero with the fidgets (fidgets.css), then the Ideathon (priority) in an indigo band, the
 * conference in a teal band, comfort badges, a magenta updates band, footer.
 *
 * Colour and type come only from the tokens in neurox.css, so every BRAINS
 * A11Y axis that rewrites a token reaches this page. Nothing here redefines a
 * token the axes own (--bg, --surface, --ink, --ink-muted, --line, the font
 * names), because this file is unlayered and would beat the axes.
 *
 * The bands keep fixed colours in both themes; each pair was measured (see
 * neurox.css).
