// test/content/op_orchd2.test.js — the 自选 operator kit of 焰狐龙梓兰 (char_1048_orchd2, 6★ 重射手; kit
// server/sim/content/kits/ops/op-orchd2.js), fielded the production way (a DIY slot + its `diy` pick, simdata getDiy) in

// “梓兰特制箭靶” at stage 1 (tier 5) / 3 (tier 6). Numbers from data/backups.json; the skill clips' moments from the kit's
