/* 360Interview.ai — hand-written stylesheet (no build step).
   Light utility-site look, deliberately distinct from both the subcue.ai
   dark-indigo product site and the subcueai.com editorial corp site.
   Accent: deep teal, single hue family. System font stack, no webfonts.

   Cascade note (learned the hard way): the nav CTA is both `.nav-links a`
   and `.btn-primary`. Type-qualified selectors like `.nav-links a` (0,1,1)
   outrank single-class ones like `.btn-primary` (0,1,0), so every nav link
   rule is scoped with :not(.btn) — never restyle `a` inside a container
   without excluding buttons. */
