Focusing a field visibly reflowed its label: "MENSAJE *" turned into
"Mensaje *" in a lighter face under the cursor. @pi/ui applies the
theme's label typography under `:not(.mdc-text-field--focused)`, so
text-transform, letter-spacing and weight all fall away the moment a
field takes focus. Restated without that guard. Colour is left alone --
Material tints the label on focus and that part is wanted.
The textarea was also drawn twice, once in the error colour and once in
the gradient, the two outlines offset from each other. Both take their
radius from `--pi-theme-field-radius`, which the `alternative` shell
sets to 999px: right for a 48px input, a stadium on a 112px textarea. A
fixed radius makes the two shapes coincide.
Both only appear in states the previous fix did not check -- it verified
the resting form only. Measured now in error+focus: all four labels
uppercase at weight 700, and the textarea's ring and outline both at
20px.
