Define explicit original, mixed and excluded file scope, credit nueex, and
preserve historical MIT grants and third-party notices. Keep libjbc's
redistribution permission unresolved and exclude third-party fonts, branding
and imagery from the original-work grant.
Retain the latest upstream build fixes and removal of obsolete tools.
Application/build edits are licensing comments only; the production ELF and
all 35 object files match the baseline byte for byte. No binaries or release
artifacts are included.
