Jyotisha/frontend/tests/rectification-range-bar-20260916.test.ts

/**
 * D10 (2026-09-16): the credible range is promoted to a bar that is on screen at
 * every width, and the board's five folds collapse to two.
 *
 * What these tests are really guarding is the honesty rule, not the layout.
 * Every figure on that bar has to be one the server already computed — see
 * frontend/docs/VOICE.md rule 2. The narrowing-progress readout the brief asked
 * for is deliberately absent because no projection carries it; the assertions
 * below keep it absent rather than letting someone add the arithmetic later.
