/* ============================================================
   V9 Home — "The Vault". Your collection in 3D obsidian space: top cards fan at
   depth, the deck parallaxes to the pointer, and the focused card lifts forward,
   faces you, holo-foils live, while its neighbours spread aside. Card = position
   (animated); .inner = pointer tilt (instant) so the two don't fight. Card art
   is the only colour; yellow rationed to rank + the HUD's "today". Heavy foil is
   display:none until a card is focused (only one composites it). Scoped .v9-vault.
