#3598988 Numeric, text and miscellaneous element fields
Expose configuration for numeric, text, color, details, container, signature and telephone elements, and validate telephone submissions.
- Numeric: min/max/step and readonly via a WebformElementNumericBase interface; range output; number size, placeholder and autocomplete.
- Text: character/word counter and input hiding.
- Color size, details open, container randomize, signature readonly.
- Telephone: international picker and validation fields, plus phone-number validation on submission.
The numeric min/max/step fields change from Int to Float so decimal bounds and steps round-trip; see the change record.
