/*
 * Nurtura marketing site
 *
 * Single stylesheet, no preprocessor, no framework. Plain CSS custom
 * properties for the brand palette + a system-feeling Inter for type.
 *
 * Layout philosophy: generous whitespace, sage as the only saturated
 * colour, phones tilted slightly so the marketing rhythm feels human
 * rather than rigid. Mobile-first; desktop layouts kick in via min-width
 * media queries.
