/* Northlight — design system
 *
 * Register: a private clinic in a good building. Calm, cool, precise, adult.
 *
 * The med-spa category has its own vocabulary of cheapness and it is loud:
 * rose gold, script, "glow up", before-and-after grids of strangers' faces,
 * countdown timers on package deals. None of it appears here. What replaces it
 * is north light — cool, even, unflattering in the way clinicians actually
 * want — plus a lot of white space and type that behaves.
 *
 * Deliberately no faces. A concept clinic showing invented before-and-after
 * results would be the single most dishonest thing this portfolio could do.
