Brutalist Textarea

Availability: @proto.ui/prototypes-brutalist@0.2.0 is published under npm latest as part of v0.2.0. Lifecycle: P-BRUTALIST-TEXTAREA and its inherited Base protocol remain draft; that is historical release information. The preview below is the successor draft recipe and does not claim a new release or an active protocol guarantee.

brutalist-textarea-root is a direct visual composition over Base Textarea. It keeps the same single physical native <textarea> and adds no new interaction, state, event, accessibility, or ownership protocol.

All behavior comes from base-textarea-root: defined controlled/uncontrolled value ownership, normalized valueChange and change signals, normalized IME composition events, composition-safe controlled restoration, native textarea prop projection, physical focus/blur methods, and textbox name/description accessibility projection.

The Brutalist prototype therefore retains Base’s contentless ownership boundary. It does not add children, form submission ownership, rich-text editing, status/live-region semantics, or any second physical control.

The entire delta is visual:

• native resizing remains host- or consumer-owned, with no automatic height measurement
• 5px rounded geometry
• an 80px minimum height, 12px horizontal / 8px vertical padding and text-sm line height
• static main/main-foreground text selection
• a flat neutral surface
• ink text and border
• DM Sans 500 text without an outer shadow

These styles are applied directly to the Base-backed native textarea. They do not create another protocol layer or change the normalized event payloads.

• Prototype: P-BRUTALIST-TEXTAREA
• Base protocol: P-BASE-TEXTAREA
• Source: packages/prototypes/brutalist/src/textarea

The recipe follows Neo 3306a802 Textarea. Placeholder/invalid styling remains outside the current projection; fresh browser pixels and native-host evidence remain pending.
