---------
All the settings that make ONE CLUB's copy of this app different from another
club's copy live here. When we turn this into a true multi-club template,
this is the file each club gets its own version of (kept OUT of git so
template updates never overwrite a club's personalisation).

For now, while we're building the single-club template, sensible defaults
are hard-coded below. Nothing here needs to change until you're ready to
actually deploy a real club.
