   8. Legacy compat layer (Pass 8, Phase 6f)

   Shell-swapped pages kept their body markup byte-identical per the
   copy guard. That means legacy classes like .lf-hero, .lf-h1, .post-card,
   .tool-card, .form-input, .faq-panel are still in the DOM but their old
   inline <style> block was stripped by the swap. Rather than rewrite each
   page's body (nine files), map those classes to Studio grammar here in
   one place so every menu-bar page inherits the Studio look through the
   same tokens the rest of the system uses.
