/* SleeperLot — "measurement bench".
 *
 * The design direction comes from the product's own thesis rather than from a website
 * genre: this is an instrument that reports ranges and refuses to guess, so the page is
 * built out of the vocabulary of measurement — ruled edges with tick marks, a bone-paper
 * ground, ink, and one instrument blue used only where a number is being asserted.
 *
 * The signature element is the interval bar (.iv): every price claim is drawn as a band
 * with the observed value plotted on it, so a range reads as a picture instead of a pair
 * of numbers. It is the one loud thing; everything around it stays quiet.
 *
 * Data colours were validated with the dataviz palette checker against the paper surface
 * (#F5F4EE): band blue, miss red and gain green clear the lightness, chroma,
 * normal-vision and 3:1 contrast gates. Green vs red sits in the CVD warn band, which is
 * why every good/bad mark on this site also carries a word or a sign — never colour alone.
