/* ==========================================================================
   Shared responsive shell for full-screen MODULE DETAIL views
   --------------------------------------------------------------------------
   One pattern for every full-screen module overlay (To-Do, Reminders, Notes,
   Calendar, …) instead of per-screen hacks:

     • <=640px  → keep the existing MOBILE layout (single column + corner FAB).
     • >640px   → DESKTOP: fill the width up to a sensible max, with real
                   padding — no phone-width column floating in a huge gutter —
                   and a labeled "New" button in the header instead of the FAB.

   Loaded LAST (after styles.css / calendar.css), so these single-class rules
   win over each module's own `.*-focus-inner { max-width: 760px }` base rule
   without needing !important. Each module opts in by adding `module-detail` to
   its root <section> and `module-detail-inner` to its inner container.
