"""Working-hours helpers.
|

|
|
|
|||
|
|
Working hours are stored per tenant as:
|
|||
|
|
{"mon": [["09:00", "13:00"], ["14:00", "18:00"]], ..., "sun": []}
|
|||
|
|
Multiple intervals per day model lunch breaks. Missing/empty day = closed.
|
|||
|
|
All computations happen in the tenant's timezone.
