🎯 New puzzle library

✨ 60 hand-made endgames (harbor-001 to harbor-060): one main + one advanced puzzle per day, each with its own title and star rating
🔁 30 days without repeats, then it loops back for review; a puzzle already in progress is never swapped
🏅 Two goals: Logic Breakthrough (prove one cell is safe from the visible numbers) and Clean Sweep (clear every safe cell)
⚡ Feel

♻️ Numbers appear the instant you tap, even cross-region; flags and chords are instant too
🚀 Opening a puzzle, starting a new round and finishing are much faster (opening ~2s → 0.3s, finishing ~1.3s → 0.4s)
🐛 Fixed the Logic Breakthrough lag where a tap took a second or two to show anything
💡 Hints and review

💡 Three-step hints: which numbers to look at → which rule to use → the exact cell
📖 Replay your solution step by step with the clues used; mine-count puzzles also show the board total
⚠️ Heads-up

⚠️ In Logic Breakthrough, tapping a cell you cannot prove safe ends the attempt — that is the rule; use the hints when unsure
⚠️ Your flags are notes only and never count as proof, so a wrong flag breaks nothing
Happy sweeping! 🎉
