Update Concept: Echo Resonance – Second-stage Redstone Expansion

This concept is named Echo Resonance, acting as the second major expansion for vanilla Redstone. The idea is inspired by echo shards and official news about upcoming deep dark content updates. Suggested content: 1. Add functional decorative electronic blocks: Redstone-controllable computers and mobile phones. Unpractical items such as air conditioners are excluded. ​ 2. Introduce more advanced Redstone components for machine builders and map creators. ​ 3. Establish more mechanics linking echo shards and deep dark biomes to Redstone circuits. This expansion will enrich technical builds, mechanism designs and puzzle map production.
