Added

• Mastery progression extended to Level 15 for furnaces, blast furnaces, and smokers, on top of the 1.0.0 level set.
• Heat Retention Mastery (Lv 11) — 35s fuel-out window with cooking progress retained; refuel and the furnace resumes exactly where it stopped. Heat Capacity Mastery (Lv 15) holds heat indefinitely.
• Thermal Overdrive IV (Lv 12, +16%) and Overdrive Mastery (Lv 15, +20%) — additive speed model, total factor up to 1.60 with Momentum.
• Thermal Momentum II (Lv 13, cap +30%) and Momentum Mastery (Lv 15, cap +40%).
• Refining II (Lv 13) — every 5th smelt yields a bonus ingot, +2 bonus per proc; Refining Mastery (Lv 15) — every 4th, +3 bonus per proc.
• Perfect Cooking II (Lv 13) — every 5th eligible food is Perfectly Cooked; Perfect Cooking Mastery (Lv 15) — every 4th, and every 3rd perfect result upgrades to Masterfully Cooked: +2 hunger and +0.5 extra saturation (Perfectly Cooked remains +1 hunger / +0.1 saturation).
• Recipe complexity XP multiplier — Advanced 1.15 / Rare 1.30 / Exceptional 1.50, capped at 2.00.
• Per-recipe discovery bonus — +5 XP per newly discovered recipe, up to 25 discoveries.
• Difficulty XP Multiplier — Easy (0.65) / Normal (1.0) / Hardcore (1.5) presets scale the XP required per level.
• Smart Filtering (Lv 14) — Advanced Recipe Lock filter slots become a pure allow-list and generalize to the placed item's tag (place iron ore and the slot accepts every ore, vanilla and modded); indicator shown on the HUD.
• Rare XP rolls — Lucky Mastery (0.009% chance) doubles, or Perfect Mastery (0.001% chance) triples, a recipe's Mastery XP; both configurable.
• In-GUI lock and filter slots for Advanced Recipe Lock, alongside the in-screen HUD.
• NeoForge 1.21.1 support alongside the existing Fabric and Forge builds.
• 1.20.1 architecture rework — mastery state is stored on the furnace item stack, matching the 1.21.1 behavior for break/place persistence.
• Stored-XP capacity grows to 45 vanilla levels at max tier.
