A string argument renders as a single-line `<input>`, which swallows Enter —
so a value containing newlines could not be typed at all.
Each string field now carries an enlarge button (ImEnlarge2) to the left of its
clear button. Clicking it swaps the input for an autosizing text area that keeps
the field's value, label, and length constraints. It is deliberately one-way:
shrinking back would have to either discard newlines the user typed or keep a
value the field can no longer show, and both are worse than staying enlarged.
Enlarging is per-field and resets with `resetKey`, so it cannot carry across to
another tool's same-named field.
