/*
 * Nusatiara custom styles.
 *
 * Layered on top of the locally bundled Bootstrap 5.3 build; only layout,
 * spacing, theming, and the drawer behaviour that Bootstrap does not cover
 * are defined here.
 *
 * Colour system: the site is purple, built from #C4A4DA (the lavender in the
 * middle of the scale below). Lavender is the brand surface/accent colour,
 * while the deeper purples carry text and small solid fills so every pairing
 * used here stays readable: white on lavender is only ~2.1:1, so labels on
 * lavender use --nt-accent-contrast instead. Sign out stays maroon on
 * purpose (docs/04, section 6).
 *
 * Reference: docs/04-nusatiara-layout-navigation-spec.md, sections 2, 5, 6.
