/* Mobile Usability Pass v1 - Training Room (both the pre-match Setup screen and
   public/playtest.js's in-match board). Nothing here existed before this pass; none of
   these selectors had any responsive CSS. The board rules are shared verbatim with
   PvP's board markup (the #pvp-me- and #pvp-opp- prefixed selectors), so those fixes apply there too at no extra
   cost. Deliberately placed at the END of the file, not near the other breakpoints
   above - every selector below has its own unscoped base rule defined later in this
   file than the other breakpoints' original location, and CSS resolves equal-
   specificity ties by source order regardless of media-query nesting, so a scoped
   override placed *before* its own base rule loses the tie and silently never applies
   at any viewport width. Confirmed as a real bug this way (not device-specific) via a
   real device screenshot showing the override having no visible effect at all. */

/* Mobile Usability Pass v1, follow-up (app-wide header/nav) - found via the
   Cards/Collection/Decks/PvP survey appendix, not part of the original Training Room
   scope. .app-header (.brand | .app-nav | .header-actions) has never had any wrap or
   overflow handling at any breakpoint - at a real ~390-412px phone width, the logo (40px)
   + 5 icon-only nav buttons (~40px each + gaps) + the two header-action buttons add up to
   roughly 390-400px on their own, before the header's own side padding, meaning a tab
   (worst case, PvP - the last one) could become genuinely unreachable with no way to
   scroll to it, since body/.app-layout both have overflow:hidden. Placed at the true end
   of the file (same reasoning as the block above - every selector here has its own base
   rule, and the existing 768px breakpoint's .app-header/.nav-btn/.brand-text rules,
   defined earlier in this file - all correctly overridden by placement order alone). */

     width (min-width:0 - the same flexbox min-width:auto trap already hit and fixed for
     .hand-row in the original pass) and become horizontally scrollable instead - this
     guarantees every tab stays reachable via a swipe even if not all fit on screen at
