A coin per realm

Every realme rides its own coin — same grouping language, a different key (which tiles, in which tiers) and its own accent glow + hub gem. Different realm = different island vibe.

Read a key: single = the realm's Orientation tile · a pair = a type-2 (two matching tiles) · a trio = a type-3. Blue = thin tiles, orange = fat. The pattern tells you exactly what to collect for that realm. Same engine (realm_coins.py) — pass any key.
