Glasgow Interface Explorer revC — design source pack

revC3 board, shared CAD libraries, revC case designs and relevant upstream documentation. Earlier boards and the revD design are excluded.

84 pinned upstream files. Files under sources/ are unmodified. Their original paths and licence notices are retained. See manifest.json for provenance, revisions, external sources and exclusions. SHA256SUMS covers the bundled upstream files.

We have not built and tested a reproduction from these files.

Known gaps:
- No revC3 BOM export was found in the pinned output folder. BOMs from earlier revisions must not be substituted without checking the revC3 schematic.
- Factory flashing is documented, but the upstream assembly section is explicitly unfinished.
- Case files are labelled revC. Fit and fabrication output have not been independently checked against revC3.
