One job: hold pointers to single external resources worth a step — a page, a PDF, a tool — with enough context to decide fit without opening them.
Rules
- Stamp from
../../_templates/external-link.md. - One link per file. The summary says what the teacher gets and why it is worth their time.
- Verify the link loads before marking
status: approved. - Sources with many useful parts are not links — they are
../30_providers/.
