Audience: Team owners, team leaders.

Short answer: Browse the Coaches Directory at
/coaches/, find the coach, click Invite, and pick
which of your teams to add them to. Coaches who accept land on the
team as a Coach with read-only access to balances, the team
ledger, and the attendance report.

Step-by-step

1. Go to /coaches/ (linked from the main nav and the team
   leader's quick links).
2. Browse the directory. Each card shows the coach's name and which
   team(s) they're currently coaching, so you can see at a glance
   who's already taken before inviting.
3. Click Invite on the card you want.
4. If you run multiple teams, a dropdown lets you pick which team
   to invite the coach to.
5. The coach gets:
   - An email invite, and
   - (If they're logged in) an in-app + push notification.
6. They click Accept and land on your team — with the Coach
   role applied.

What a coach can see (read-only)

• Player balances — who owes what.
• Team ledger — every transaction on the team.
• Attendance report — who's been showing up.
• A new Coach sidebar section on team pages with quick links to
  these three views.

A coach cannot:

• Edit transactions, void bills, or post charges.
• Change roster, lines, or event registrations.
• Manage chat rooms, invitations, or settings.

Notes / gotchas

• Multi-team owners see the team-picker dropdown on every coach
  card — single-team owners skip straight to the invite.
• Coaches still need an account. If they don't have one yet,
  the invite email walks them through signup; the coach role is
  applied as soon as they accept.
• The directory is opt-in. Coaches register themselves at
  /coaches/register/ to appear in the directory; they can also
  unregister at any time.
