Summary: Multi-line free-text entry in the same box as the text field; resizes vertically only and can show a character count.

Use the pinned approved default profile. Pending roles in that profile use-and-report their decision IDs; this does not approve them. Proposed profiles are preview-only and blocked for delivery. Heritage profiles are historical-only. Deprecated or heritage roles are blocked for new approved-profile mappings. Consume roles within their documented scope, never primitives. Release numbering does not approve profiles or tokens.

State dependency disclosures: D-007

States: default, hover, focus-visible, placeholder-shown, filled, required, invalid, invalid+focus-visible, disabled, read-only
  default: 1px {color.border.control} on {color.surface.input}; text {color.text.default} [—]
  hover: background → {color.interaction.hover.bg}; border unchanged [cursor: text]
  focus-visible: border → {color.border.active}; ring 1px dashed {color.interaction.focus.ring} at −2px [the ring]
  placeholder-shown: placeholder in {color.text.placeholder}, italic [italic]
  filled: as default with a value [—]
  required: `*` after the label in {color.status.danger.text} plus visually hidden "required" [`required`; the mark]
  invalid: border 2px {color.status.danger.border}; message with the ✕ glyph; a count past its limit turns {color.status.danger.text} with the glyph [border width 1 → 2px; glyph; `aria-invalid`]
  invalid+focus-visible: the 2px danger border and the ring in {color.interaction.focus.ring-container} at −4px [double boundary]
  disabled: text {color.text.disabled}; border {color.border.disabled}; background {color.interaction.disabled.bg}; no resize handle [`disabled`; cursor: not-allowed]
  read-only: no box: 1px dotted {color.border.divider} bottom edge on {color.surface.canvas}; no resize handle; selectable [`readonly`; dotted edge]

Keyboard:
  Tab / Shift+Tab: Moves focus in and out; Tab never inserts a tab character.
  Enter: Inserts a line break; never submits.
  Ctrl+Enter / Cmd+Enter: May submit the owning form when the host binds it; announced in the help text.

ARIA: native <textarea> with <label> (https://www.w3.org/WAI/ARIA/apg/practices/forms/)
Responsive: Fills its field container with min-width 0 and width 100%; the resize handle is vertical only so the box can never widen past its container at 320px. RTL keeps the handle on the inline-end corner.
Portability: native <textarea> plus <label>; rows="3" minimum; resize vertical; the count is a live region with aria-live="polite" updated at most once per second; the dashed ring through outline, never box-shadow.
  native: GTK4 TextView inside a ScrolledWindow with a frame.
  native: Qt QPlainTextEdit stylesheet; invalid through a dynamic property selector.
  native: Terminal UI: bordered multi-line box; the count in the bottom border.

Rules: use only these values; no invented colours; radius 0; borders 1px (2px emphasis); focus is a 1px dashed ring, selection is a fill;
do not restyle unrelated elements; report deviations per agents/consume.md; record theme.lock.json at the pinned revision.
