// test/content/feedback5-we2-raid-148.test.js — 0.2.0 WE2 #3 (GitHub #148 「突袭近战干员部署在高台」, a battle screenshot on the
// 深水区 map): reproduced on every battle stage — a melee 突袭 member's jump (content/bonds/addon/battle.js raidTile:
// grid.canStand for its position) lands on low ground only, never on a 高台; on 战场#08 (act2 m04) it may land on a 围墙 tile
// (tile_fence_bound: LOW, buildable ALL — deployable, it attacks from there and blocks no ground enemy, DESIGN §21.23), which
// the board draws as a raised concrete area inside an orange railing: what the screenshot most likely shows.
// Run: node --test test/content/feedback5-we2-raid-148.test.js
