/* ---------- tablet (native shell only) ----------
   Same gate and scoping as the block at the end of app.css - see the long comment
   there for why `min-width: 700px` (above the widest iPhone portrait viewport at
   440pt, below the iPad mini's 744pt), why `min-height: 600px` (a width-only gate
   also matches an iPhone in landscape, 852-956px wide but at most 440px tall; the
   shortest iPad viewport in either orientation is 744px), and why `html.compact`
   (set only by the native shell and mobile-web phones - here in settings.js init() -
   so the desktop site at swedishflashcards.app, built from this same stylesheet, is
   untouched).

   Width only, matching custom_cards.css so the column doesn't jump when navigating
   between the two pages. No vertical centring, unlike app.css: the panels overflow
   every tablet viewport (this page scrolls on a 13" iPad in both orientations), so
   `safe center` would degrade to flex-start anyway. It is a cap, not a floor - these
   three elements are already width:100%, so on an iPad mini in portrait (744px wide,
   712px content box) they stay at 712px and nothing overflows horizontally. */
