   Styles for LMS Page content authored as HTML fragments in TinyMCE.
   Loaded globally in App.razor and also fed into the TinyMCE editor iframe
   via editor.js content_css, so admin preview matches student view.

   Class vocabulary follows the .lesson-* and .lesson-h5p-* prefix used in
   the canonical Page 1 sample (courses/Accounting Tech/1 CAA/.../c. HTML/).
   The HTML stays structure-only; all visual polish lives here.
