-- Dump every species' ADVANCED palette and its shiny-shifted twin, as JSON.

--
-- Run from the PROJECT ROOT.
--
-- The game's battle pics are four-shade DMG grey (0/85/170/255) -- there is
-- no colour in the art at all. Under ADVANCED (`redpp`) the colour comes
-- entirely from a per-species palette applied over the top, which is why a
-- shiny SPRITE is a shifted palette rather than repainted art. This dumps
-- both halves so a comparison sheet can be built from them.
--
-- Reads the real generated data directly rather than going through
-- PaletteFX: the headless fixture dataset carries FIXMON placeholders, not
-- the 151, so a dump driven through it is of nothing.
