/*
 * A PARAMETRIC DRAWING, not a laid-out surface. Every measure here is a rounded
 * fraction of the badge's own width — `size` is the one datum — so each arrives
 * as a custom property the component computes (§5 rule 11) rather than as a
 * `calc()` naming lengths of its own. That is also what keeps the rounding: at
 * 26px the rule is 2px, and a fractional 1.5 renders as a grey smear.
 *
 * The type is the one measure that does NOT scale freely: the label and the
 * stamp land on the ramp's nearest rung and are DROPPED under its floor, which
 * the component decides — a fraction of 26px has no rung to take.
 * `--lotics-file-badge-tracking` is the component's own micro-typography and is
 * declared here, beside the drawing it belongs to.
