Linesman rotas that run themselves

Replace the WhatsApp-and-spreadsheet shuffle. Parents sign up once, dates are shared out fairly, and when someone can't make it, cover is found automatically - by email and WhatsApp.

• 1. Add your season - every Saturday in one go, skipping half-terms.
• 2. Share one link in your team group - parents sign up in 30 seconds.
• 3. Fair allocation - nobody twice in a row, everyone does their share, holidays respected.
• 4. Dropouts sorted - "Can't make it" messages the next parents in line; first to tap gets it.
