Storage rework, difficulty pacing, boats and fishing.

Storage

• Backpacks! replaced with Tiered Backpacks. The old mod built its backpacks from a re-skinned command block and registered no items at all, which is why they never showed in JEI and rendered as a command block for anyone without the mod installed. Tiered Backpacks registers six real items on a leather -> copper -> iron -> gold -> diamond ladder, matching Iron Chests.

Difficulty

• Added Hostile Mobs Improve Over Time. Mobs scale with each player's own playtime, so newcomers start unbuffed while veterans face harder mobs.
• Retuned from the default 20 minutes per level to 12 hours, with the level cap lowered from 100 to 20 so the curve actually completes over a season rather than needing 1,200 hours.

Boats and fishing

• Boat Item View: see your held items while the boat is moving.
• Lava Boats: crimson and warped boats that ride lava.
• Upgradable Fishing Rods: rod tiers up to netherite.
• XPlus Autofish: auto-reel and recast, client-side only.

Not included, deliberately

• ly-fishing-expansion and fishing-frontier register zero items and re-skin vanilla ones through components, the same pattern that made the old backpacks invisible to JEI.
• lava-boat-clutch-fix restores a mechanic Mojang fixed in 1.21.5.
