pub const MAPS: usize = 4;Expand description
How many maps every curated table carries.
Exactly four, always — a figure with fewer duplicates one at probability
0. The shader’s map choice is an unrolled four-way branch (the reason
Basis::masks uses one-hot selectors rather than
indices: WGSL will not dynamically index outside addressable storage and the
backends disagree about the rest), so the count is structural rather than a
convenience.
