/* ShapeUp — Exercise Log: History tab styles.
 *
 * Ported from the Claude Design mockup (example/shapeup-history.html) but recut
 * to the project's tokens/conventions (see exercise.css :root + .xl-* sizing) —
 * Montserrat, the shared color vars, and the same card radii/shadows as the Log
 * tab. Split colors are no longer data-driven per calendar day (a plain split
 * label is printed instead) — --split / --split-tint now only reach
 * .hist-session-pick, the session list below the calendar.
 *
 * Class prefix: .hist-* (lives inside #xl-panel-history > .xl-hist). */
