Match mobile inputs to the data
Use semantic input types, inputmode, and autocomplete without assuming one browser keyboard.
Choose form markup from the meaning of the data. A convenient mobile keyboard is one result, not the only goal.
The decision: assign the correct input type first, add inputmode when a text control needs a particular input hint, and add autocomplete when the field collects a recognized user detail.
