NoRiskClient/nrc-server-mappings — reverse-engineered prompt

Build me a small JavaScript project for NoRisk Client server mappings. I want server owners to be able to add their server info, icon, banner, and other display details in a clear format, then run one command to check that everything is valid and merge all servers into one output that the client can use.

Please include a servers folder with an example server, a scripts folder with validation and merge scripts, and docs that explain how someone should create a new mapping, what the manifest should contain, and what image sizes or formats are expected. The validation should catch common mistakes like missing fields, bad image names, wrong formats, or broken server entries.

Make it easy for a lightly technical person to follow. Add a README with setup, local testing, and contribution instructions, including the usual npm install and merge command. Use simple wording and make the generated output predictable so it can be used by the client.
