/* =============================================================================
   as-responsive.css — tablet + desktop adaptive layer for ActuallySpeak.
   -----------------------------------------------------------------------------
   HARD RULE: every rule in this file lives inside a min-width media query
   (tablet >= 768px, desktop >= 1100px). Nothing here can ever apply below
   768px, so the phone layout is exactly what it was before this file existed.
   Link it LAST in <head> (after every other stylesheet / inline <style>):
       <link rel="stylesheet" href="/as-responsive.css">

   What it does
   - Tablet  (>=768px): the centred phone column widens (~880px), card/zone/
     lesson lists become 2 columns, tile grids get more columns, type and
     spacing grow a little.
   - Desktop (>=1100px): the bottom tab bar (#u26Nav, injected by
     /as-ui26-nav.js) becomes a left sidebar; the content area widens to
     ~1120px; home / hub pages use a 2-column dashboard layout; the General
     app shell (index.html) widens and its flashcard card lays out side by side.
   Touch targets stay >= 44px and env(safe-area-inset-*) padding is kept.
   No image is ever blurred here.
