/* Mentora website — shared design tokens + components.
   One stylesheet, every page links it, so the site reads as one system.
   Dark is ALWAYS the default (matches the app), regardless of the visitor's
   OS/browser color-scheme setting — an explicit toggle click is the only way
   to switch to light, remembered via localStorage (see site.js). */
