Fix the invoice from the taxi

The client texts: the VAT line on invoice 0412 is wrong, and they need the corrected PDF before their accountant leaves at five. It's 4:35. The laptop is in the trunk.

You open the display URL on your phone with ?keyboard=true. The container's desktop appears, LibreOffice Calc still open on the invoice template. Pinch to zoom into the VAT cell, tap it, the virtual keyboard slides up, you type the right rate. Export to PDF, save into /hoody/storage/invoices.

Then you open the hoody-files URL, long-press the new PDF, copy its link, and paste it into the reply. 4:41.

No app on the phone, no cloud sync to wait for, no version to reconcile later. There is one copy of the invoice, and every device looks at it.

The phone doesn't run the spreadsheet. It reaches into the machine that does.
