   Bengali font handling
   ----------------------
   Many WordPress themes only load Latin subsets of their fonts, so
   Bengali (Bangla) text falls back to the OS's default — which shows
   as boxes/"tofu" on some Windows/older Android setups, or an ugly
   generic sans-serif elsewhere. To guarantee correct, legible Bengali
   rendering everywhere regardless of the active theme, this plugin:
     1. Enqueues Noto Sans Bengali from Google Fonts (see 
        BCAD_Shortcodes::maybe_enqueue_assets()), which have full 
        Bengali Unicode coverage.
     2. Applies it explicitly, with NO fallback fonts, to every element 
        inside .bcad-layout / .bcad-digest so they are never silently 
        overridden by the theme's own body font. */
