Which theme the board wears, decided by what is happening rather than by hand. Edit here, export the JSON, drop it on the community server next to the publisher. Index · Open the wall with the rule readout
This is what the server should hold. The publisher can either include
it in the snapshot as themeRules, or you can drop it in
this folder as theme-rules.json and the board will fall
back to it.
Rules that depend on the date or an event only fire when that thing is true. Set a moment here to see what the board would do then, without waiting for Halloween.
