/*
* Pixelmon spawn-chance calculator gadget (full-page).
*
* Mounts into <div id="spawn-calculator" data-species="..."> on the standalone
* Spawn Calculator page. data-species is normally empty there; a ?species=Name
* query parameter (used by the link on each species page) pre-fills the picker.
*
* For a chosen species and situation it shows the chance that a single
* Better-Spawner selection is that species:
* P = sum(rarity of this species' matching spawns)
* / sum(rarity of all matching spawns)
*
* Dimensions: biome, location type, time of day, weather, Y-level, light level,
* moon phase. Only the dimensions that actually constrain the chosen species are
* shown. Each shown field can be locked so "Find best chance" leaves it fixed.
* "Consecutive times" averages a cyclic block of times of day, weighting each by
* its real in-game length; with "Strict block" the optimizer only accepts blocks
* where the species spawns in every time, otherwise it reduces the block size.
*
* Data is provided by Gadget-spawncalc-data.js as window.PixelmonSpawnData.
* This file is static UI/logic; it is NOT generated. The data file IS.
