How each Cucina cost line is shared out. Default = pro-rata to sales of CPU-using sites (the catch-all — nothing can leak). Specific = ratios you set, to revenue streams. Follows specific labour = lands wherever the specific lines landed.
A live "what if sales were X% higher / lower". Top line flexes, and the variable costs that move with it — cost of sales and labour — flex too; fixed costs (rent, rates, property, fixed overheads) stay put. Nothing is saved to the scenario until you click Save as scenario.
Honest mechanics: closing a unit saves only its direct costs (labour and cost of sales). Its rent, rates, property and overheads stay with the building — if it shares premises with a unit that's still open, those revert to the survivor and aren't saved. Close every unit at a premises to genuinely exit the lease and shed its overheads. Cucina & Centro keep their full cost too (re-spread over the survivors); enter assumed central savings below if closing would shrink them.
