Stage 17 docs: round-4 UI (inline profile, double-tap/drag recall, hover-zoom, animated shuffle, lines-off board)

- UI_DESIGN: double-tap recall vs zoom, hover-hold drag auto-zoom, placing & recall
  rules, grid-lines toggle (gapless checkerboard default), animated shuffle; fix the
  stale MakeMove/Reset description (direct ✅ button + ↩️ Reset tab, no popover).
- FUNCTIONAL (+ru): optional trailing '.' in display names; profile edited inline.
- PLAN: robot early band [1,5]→[3,10] (#14); round-4 refinements + deferred #2/#16.

+    a cell ~1 s auto-zooms** there (#3/#10); **🔀 Shuffle is animated** — tiles hop along a low parabola to
+    their new slots, duration scaled by distance, with a haptic shake (#9); a **lines-off board** Settings
+    toggle (default off) renders a gapless checkerboard with rounded, right-shadowed tiles, reclaiming
+    ~14px of width (#12). **Deferred (discussed):** board **pinch zoom** (#2) — it fights both the native
+    scroll and the new one-finger drag-back, so it stays dropped in favour of double-tap + hover-hold zoom;
+    **robot win% in the admin game detail** (#16) — needs the seed-derived play-to-win decision exposed
+    across the game/robot package boundary, to be picked up when that seam is added.
