/* ==========================================================================
   MainMenu landing page

   The page is built around one artefact: the receipt. Paper is the resting
   surface, ink is the counter, and the only warm colour in the system is the
   amber the app already reserves for money leaving the till — so the schedule
   chips and the instalment line on the receipt are the warm points on an
   otherwise cool page.

   Everything is written with logical properties: the same stylesheet serves
   `dir="rtl"` (Farsi, the default) and `dir="ltr"` (English).
