// Real-server browser E2E of 0.2.0 自选编队 end to end (research 0.2.0 §2; the owner's decisions of 2026-10-05): the
// 自选编队 tab of the 干员调配 overlay fills the first tier-5 slot with 推进之王 (real clicks: the slot, the operator, S3, the
// SOL-X module, 确认; persisted in localStorage; room.diy → session → seat → the next match's m.private.diy); in the
// match the 调度中心 is at level 5 and the shop sells the slot as 推进之王 with the 「自选」 badge; bought, the hand piece is
// tagged 「自选」 and draws 推进之王's model; deployed, the detail card shows 推进之王 with the pick's skill; and in the
// browser's own battle (client-side combat) the unit is the operator — the b.start spec carries the pick (`diy`), the
// local sim fields char_112_siege with its operator kit, and the battle view draws its Spine model.
//
//   SP_E2E=1 node --test test/ui/diy.e2e.test.js
//
// The server is test/e2e/fastServer.mjs with its starter-kit hooks (no starter operators, the 调度中心 at level 5 —
// SP_START_LEVEL —, the tier-5 DIY slot in the first shop slot, 20 funds); everything else is the real match engine and
// the real UI driven by real mouse input. Screenshots: test/e2e/out/diy-*.png.
