Adds Atmospheric Data Cores, Refined Sulfur, Volcanic Isotopes and
Subsurface Ocean Samples, and the new producers and destinations for
existing goods at Venus, Io and Europa.

 Spec: `memory-bank/change-requests/CR-016-venus-io-europa-belt.md` (received as "CR-015 … Phase 15"). New decisions recorded as plan §0.5.100–0.5.105.
 
 - [x] **Step 16.1 — Content: new locations.** Venus Cloud City (cloud platform, atmospheric, 108M km at 110°, range factor 1.0, fuel × 1.3, bay 20,000), Io Sulfur Works (new type `orbital-station`, `vacuum` landing so any ship can land, 0.42M km out from Jupiter, factor 1.2, fuel × 1.0, bay 70,000) and Europa Ice Station (new type `surface-base`, `vacuum`, 0.67M km out from Jupiter, factor 1.3, fuel × 0.7, bay 70,000); all undiscovered, selling fuel, with the CR's shippers and class mixes. Pulled forward so the game keeps working: each new place's Standard good (Cloud-Grown Botanicals at Venus, a new good; Mail & Parcels also produced at Io and Europa), since boards can't be generated where nothing Standard is made; and the three body sprites in the art manifest, with their generated art (the belt is still 16.5). The balance check's first Market purchase moved from 64 to ~92 min (the Clipper's landings decide it, and Venus changed which first contacts boards offer); the user widened the window to 45–95. Tests: `packages/content/test/fixed-map.test.ts` (Earth/Moon–Venus ≈ 200, Venus–Mars ≈ 332, Venus–Ceres ≈ 520, Venus–Jupiter ≈ 885, Ceres–Io/Europa ≈ 393, all within 2 %; the Jupiter system within 1.1M km; Io and Europa ride with Jupiter at their offsets; the three undiscovered, selling fuel, not Hardened; only Earth and the Moon start discovered); `locations.test.ts` (eight locations; fuel prices ordered Jupiter < Europa < Ceres < Io < Moon < Venus < Mars < Earth). Updated: bundle count, first contacts may go to Mars or Venus, the CR-007 class-mix baseline measured on its original five places, orbit rings for every body but those riding a parent, the Market reach line now listing Venus.
-- [ ] Step 16.2 — Content: goods
+- [x] **Step 16.2 — Content: goods.** New goods: Atmospheric Data Cores (High-Value tier 2, Venus → Earth), Refined Sulfur (Heavy, Io → Earth, Mars, Venus), Volcanic Isotopes (High-Value tier 3, Io → Earth), Subsurface Ocean Samples (High-Value tier 3, Priority, Europa → Earth); Cloud-Grown Botanicals came in 16.1. Water Ice and Liquid Oxygen are also made at Europa, Industrial Chemicals at Venus; Water Ice goes to Io and Venus, Liquid Oxygen to Io, Habitat Prefabs to Io and Europa, and Packaged Food, Consumer Goods, Mail & Parcels, Medical Supplies, Electronics and Machine Parts to all three new places. Balance medians: first purchase 92.3, discovery 48.9, loan 160.5, four ships 147 vs 156. Tests (`packages/content/test/goods.test.ts`): the five new goods with their classes, tiers and routes (Sulfur has no tier of its own); every location makes a Standard good and wants at least one; each new place is a destination for at least five goods; the new producers on existing goods.
