- New GET /api/players/playtime (authed): reads each vanilla stats file
under /home/minecraft/server/world/stats and maps uuid→name via
usercache.json. Returns playtime in ticks and hours, plus file mtime
as "last seen". Memoized 60s via lib/cache#memoAsync.
- New PlaytimeLeaderboard card in the Players tab:
- Rank, avatar (click → PlayerDrawer), relative last-seen, hours.
- Top 10 by default with toggle to show all; combined hours badge.
- PlayerDrawer surfaces the player's total hours + last-seen using the
same cached playtime query, plus fills in UUID if the player is not
in ops/whitelist/banned.
- lib/time.ts: formatHours() — minutes under 1h, "H.Hh" under a day,
"Dd Hh" above.
- Analytics sparklines gain hover/touch tooltips:
- Timestamps threaded through from each MetricEntry.
- SVG overlay captures onMouseMove/onTouchMove, computes nearest
index by x, draws a dashed guide line + focus dot.
- Floating tooltip shows HH:MM + formatted value with unit; edge
clamping keeps it in-frame at the extremes.
- Per-chart formatValue so RAM shows GB, CPU 0 decimals, Players
integer, TPS 1 decimal. Keeps the peak-player marker intact.
