- Leaderboard empty state: replace single muted line with a two-tier
"Be the first on the leaderboard." headline + body invite.
- Achievements panel: surface a first-launch hint above the grid until
the player unlocks anything, so the greyed-out rows aren't context-free.
- Volume hotkeys ([/]): emit an InfoToastEvent with the new percentage so
off-panel adjustments give visible feedback (previously silent).
