Errata 404

A correction sheet for a missing page: an interrupted column, editorial annotation, and a neatly numbered route back.

The design brief behind this component — reuse it to regenerate, remix, or explain it.

Build a 404 like an editorial correction sheet on warm paper (#f1eadb) with brown ink. A mono ruled masthead identifies THE CORRECTION SHEET and No. 404. Beneath it, a narrow margin holds ERRATA, a small annotation and a bent arrow; the main column carries a large Instrument Serif headline. Supporting copy shares a row with an interrupted text column represented by fine rules and a TEXT OMITTED annotation. A numbered index of ordinary recovery anchors follows; hovering or focusing a link draws an underline from the left over 250ms. End with a quiet ruled colophon. This is a missing-page composition, not a document browser. Keep all text semantic, omit decorative marks from accessibility, and never require motion to navigate. On a phone move the margin note inline, remove the decorative empty column and keep the source reading order. Reduced motion makes link feedback instant. Implementation requirements: Use React and TypeScript. Keep the component self-contained, with uniquely scoped CSS and no animation libraries. Include required imports, styles and font setup in the result. Interaction: In Vitrine and the usage example, activating a recovery link is simulated locally and never changes page. In a consumer application, caller-supplied anchors remain usable. Numbered recovery anchors underline on hover or keyboard focus. Motion: 250ms underline scale; reduced motion removes the transition. Accessibility: Semantic headings and native links/buttons, visible focus, decorative geometry hidden from assistive technology. Independent instances; honour reduced motion. Responsive behavior: Fluid layout and wrapping text at 320px through desktop. Page compositions stack intentionally on narrow screens; recovery links remain visible. Touch: Normal taps activate all actions. Pointer-only decoration is optional and fixed on touch. Preserve keyboard access, visible focus and reduced-motion behavior. Keep fictional demo data and simulated service calls in a separate usage example; expose callbacks for real actions and recover from rejected requests. Keep usage-example links inside the demo: use local buttons or prevent navigation. Demonstration links must not navigate to Vitrine routes or open other pages; preserve real URL support in the reusable component itself. Verify the result at narrow and wide viewport sizes, with keyboard input and reduced motion enabled.

Send turns into stop while the reply streams.158Aura FieldA writing field where colour only exists while the AI is touching your text: the edge becomes a turning band of light and the words are rewritten in place, one by one, out of a soft blur.
