// GSAP 3.15.0 under Node v22.22.2; generator golden.js; root time after the frame tick: 0.
// Numbers are the golden doubles (shortest round-trip repr, bit-exact). Tolerances are the test's business
// (see design/gsap_reconciliation.md D: GSAP rounds written property values to 1e-6, so value columns need 5e-7).
// Each step is a flattened snapshot (obj.x, t1_has_parent, callbacks.0, ...), in the order the GSAP calls ran.
