/* OpenWorldEngineer: bearing fault embeddings (artifacts-bearing.html, assets/art/bearing.js). Builds on styles.css
   (tokens, .card, .seg, .note, .tip); adds only bf- classes.

   Colour: the eight true conditions. Seven hues from the dataviz reference palette in an order that passes the
   validator's adjacent checks in light and dark (orange is never paired with red: there is no red), and healthy as a
   neutral ink tone (deliberately grey: "no fault"). Eight colours cannot all be told apart pairwise in a scatter, so
   every condition also has its own marker shape, a name in the legend and a direct label at its centre. */
