Footprint coverage tested against a real HEALPix (nside=64) grid at 1° resolution, packed as a bitmask, for a gap-free fill without shipping the original multi-MB coverage maps; outlines (Euclid, HSC) are the original digitised vertex loops. Background: NASA/SVS Milky Way mosaic. All data bundled inline — no external requests (background image loads from this same page's folder). Adapted from a matplotlib/healpy tool originally by Steven Benton (Princeton).
