/**
 * The declarative Auto Viz rule table.
 *
 * `dim` / `mea` / `requires` implement the expressiveness filter (hard constraints):
 * a chart type is only offered when it can encode all selected fields without
 * fabricating facts. `score` implements the effectiveness ranking (soft ordering):
 * among legal candidates, position-encoding, intent-matching charts win.
 *
 * Score conventions — the champion of a typical intent scores in the 85–95 band:
 * - pure dimensions → table (90)
 * - single measure → histogram (90)
 * - two+ measures → scatter (93 alone / 84 with dimensions)
 * - temporal + measure → line (92)
 * - category + measure → bar (85 for the 1×1 case / 80 otherwise)
 * - geographic fields → maps (poi 95 so it beats scatter on a lon/lat pair, choropleth 86)
 * Weak-perception encodings (pie: angle, heatmap: color) stay in the 35–70 band
 * so they are offered but never become the default over a position-based chart.
