/* styles-v4.css — v0.4 six-tier grid styling (PHASE8).
   Lifted from the v0.1 mainnet reference (.tiers-grid / .tier-card) so the
   six-card picker is visually identical to the original Satoshi-Dice tier UI.
   CSS variables (--teal/--blue/--purple/--red/--mono/--display/--sans) are
   already defined in index.html :root, so this file only adds the grid + cards.
   No tier is ever .locked in v0.4 (fixed 1 TKAS bet) — the .locked rules are
   carried over for visual fidelity but unused. */
