- Footer title and favicon now track the currency: "Monero Roguelike" + the
Monero logo favicon on the XMR instance, "Wownero Roguelike" + the existing
favicon on WOW (driven by UI.updateGameTitle).
- "Choose How to Play" modal: a header explains that paying (credits/entry)
puts high scores in the Hall of Champions while free play uses the Pleb
leaderboard, and each option now says which board it feeds — on both the
no-payout (mainnet) and payout (stagenet) variants.
