/**
 * Dev-only SHOP PANEL geometry probe (real browser, via cdp-firefox.mjs):
 * boots the game, lands on the home world, forces the surface stage, opens
 * the shop, clicks "Buy/Sell", waits for the slide-in, then reports the
 * on-screen geometry of the planet HUD text + the SELL/BUY panels + the
 * sub-bar — so the panel's top edge vs. the planet text is verifiable
 * numerically. Also sets window.__SHOP_SHOT__ so a driver can screenshot
 * the moment the numbers are ready.
