/*
 * Text field — Figma "input-inline" (4041:133) and "text-form" (4041:197).
 *
 * The label starts as a placeholder centred in the box and floats to the top
 * as a caption as soon as the field is focused or filled, which is exactly
 * the Enabled -> Focus/Valid/Error transition of the maquette.
 *
 * The floating relies on :placeholder-shown, so the control always carries a
 * placeholder; the Twig component sets a blank one when none is given.
 *
 * States are driven by the real validity of the control rather than by a
 * modifier class, so a server-side error and a browser-side one look alike.
