/**
 * Converts a list of threshold indicators into colored arc segment data for
 * the threshold interval bar drawn below the gauge arc.
 *
 * Zones created (consistent with findMatchingThreshold coloring logic):
 *   [min → t[0].value]            fill-out zone  → baseColor
 *   [t[0].value → t[1].value]     zone 1          → t[0].color
 *   ...
 *   [t[N-1].value → max]          zone N           → t[N-1].color
 *
 * @param thresholds   - Threshold indicators (any order; out-of-range filtered).
 * @param min          - Chart minimum value.
 * @param max          - Chart maximum value.
 * @param midRadius    - Mid-radius of the threshold arc band; used to convert
 *                       pixel distances to angles.
 * @param baseColor    - Color for the fill-out zone (before the first threshold).
 * @param gapPx        - Circumferential gap in px between adjacent segments.
 * @param minLengthPx  - Minimum arc length in px. Gaps shrink to keep thin zones
 *                       visible; zero-width zones (duplicate values) collapse.
