Follow a case: get its emails and bell items (idempotent).

The token's user gets the case's emails and bell items when the BoardMark team answers. Only when the user asks.

Support cases = asking the BoardMark team for help. Use them when the user wants help from the BoardMark team or reports a problem with BoardMark itself (a bug, signing in, billing, a feature request) — never for the user's own project work (that is issues: create_issue, search_issues …). Every member of the token's company sees and can answer every case of the company. The BoardMark team's replies arrive in the case thread (get_support_case), and followers also get them by email. Text only: files are attached in the web app (Help → Contact support). Your writes show as "via AI agent".
