Calculate metrics from first relevant event to now (capped at 30 days) instead of a fixed 30-day window. This fixes inaccurate metrics for new users who have only a few days of data. Changes: - Add _get_first_event_ts() and _calculate_window() helpers to stats.py - Add window_days field to EggStats dataclass - Update routes/eggs.py and routes/feed.py to use dynamic window - Update templates to display "N-day avg" instead of "30-day avg" - Use ceiling division for window_days to ensure first event is included 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
