Sky Frogs

An endgame unblocker: the two Singularities nobody could ever craft are gone, the Ultimate wants 48, and kelp finds its way into the moss sieve.

Fixed

• The Water and Lava Singularities are gone - they were uncraftable (#131, reported by Dergib on Discord): both demanded 1000 of an item with zero sources on a void skyblock (kelp and pointed dripstone - no ocean, no caves, sand sieving disabled, and the fluid-pair Froglights melt to fluid rather than smelting to an item). The Ultimate Singularity now wants 48; mid-campaign players will see its recipe shrink, and already-crafted Water/Lava Singularities become inert curios. The exclusion lives in the generator, so future PF bumps cannot resurrect the pair.

Added

• Kelp sifts from moss (#131, Dergib's suggestion, accepted): the Builders' Sieve moss lane gains kelp at Ex Deorum's own 10% - with its singularity gone, kelp is decor and dried-kelp food again, exactly what the lane is for.
