/* =============================================================================
   Inventario — stock + ledger tool
   Implemented from the Claude Design project "Inventario" (2191f8ad),
   files "Inventario.dc.html" (phone) and "Inventario Desktop.dc.html" (wide).

   MOBILE FIRST on purpose: the phone layout is the base and should feel like
   an app — bottom tab bar, thumb-reachable add/remove buttons, sheets that
   rise from the bottom. The desktop design is the >=900px branch of the same
   markup: two columns, a right-hand drawer, and buttons back up in the header.

   Colors, buttons, chips, fields, cards, the sheet and the toast come from
   /ds/. What is here is this tool's layout and its own pieces.
