/* SAPD Academy — design system v3 ("realistic LMS")
   A real training-platform shell: fixed sidebar nav, white surfaces on a
   light neutral app background, Lora for headings/titles, Source Sans 3
   (self-hosted) for everything else. Navy is the primary/action color;
   gold is reserved for things an officer has actually earned or is actively
   earning — completed stats, certificates, progress fill, the "continue
   learning" resume action. It is never used decoratively.
   Lora is loaded via Google Fonts <link> tags in views.js's layout(). */
