1// The grid's one visual vocabulary, as pure tokens.2//3// Issue #5 §5.4: outputs are renderer-neutral artifacts — plans and pure style4// tokens. These numbers live in the analysis lane because both projections5// must render from the same ones or they drift apart: line weight encodes the6// hierarchy the way an MGRS grid weighs its own, the chosen path draws white7// over per-cell palette accents, and the label is a small chip spelling the8// address with its prefix faint and its final character bright.9//10// Nothing here is a colour a renderer chose. The chart adapts these into11// ol/style and the globe into materials and sprites; neither holds a width or12// a colour of its own.1314/**15 * The accent wheel.
