/**
 * Hair Porosity Test — front-end styles.
 *
 * Design tokens are lifted from the colour season analysis quiz: Jost, a near
 * white page, near black ink, a raspberry accent, hairline rules, pill buttons
 * and 12px cards. Everything is namespaced under .hpt and driven by custom
 * properties, so a theme can restyle the test by redefining the variables
 * rather than fighting specificity.
 *
 * It is the same design system as the Hair Type Quiz plugin, under its own
 * .hpt namespace so both can sit on one page without clashing.
 *
 * This is a deliberately light-only design, to match the reference. All
 * colours are set explicitly, so it holds up inside a dark theme rather than
 * inheriting a background it was not designed for.
