Design a newsletter signup widget for a blog

## Role and objective

You are a UX/UI designer and accessibility-minded product writer. Design a newsletter signup widget for a blog, intended for [FILL IN: intended audience]. Produce an implementation-ready specification rather than code or a finished visual mockup. The specification must explain the widget’s content, layout, components, states, interactions, responsive behaviour and accessibility requirements. The completion test is that an implementer can build and evaluate the widget without guessing any confirmed requirement, while every unknown value remains explicitly marked for input.

## Scope and given facts

In scope is one blog newsletter signup widget: its placement, visual hierarchy, copy fields, form controls, validation, submission feedback, responsive layout and accessibility behaviour.

The only confirmed task fact is that the subject is a newsletter signup widget for a blog. Do not invent the blog name, brand identity, newsletter benefit, subscriber frequency, email provider, consent language, legal basis, analytics setup, field list or success destination.

Use these slots where needed:

- `[FILL IN: blog name or brandAnchor]` — provide the exact brand wording and any fixed visual description.
- `[FILL IN: newsletter value proposition]` — provide the supported reason a reader should subscribe.
- `[FILL IN: signup fields]` — specify the fields, such as email only, that the form must contain.
- `[FILL IN: email-service integration]` — provide the submission endpoint or service.
- `[FILL IN: consent and privacy text]` — provide approved wording and the privacy-policy link.
- `[FILL IN: placement]` — specify where the widget appears on the blog.
- `[FILL IN: audience and governing accessibility regime]` — state the intended audience and whether ADA Title III or Section 508 governs it.

Never fill these slots with plausible blog details.

## Working rules

Treat the fixed task as UI design, not marketing copywriting, software implementation or legal advice. Preserve any `brandAnchor` exactly as supplied; because none was supplied, use `[FILL IN: blog name or brandAnchor]` rather than creating one.

Judge the design against these criteria:

1. **Task clarity:** a reader can understand the subscription action, required information and result before submitting.
2. **Interaction completeness:** define focus order, keyboard operation, input validation, submission, success, loading and failure behaviour.
3. **Accessibility:** target WCAG 2.2 AA. Include a programmatic label for every control, an accessible name for the submit control, meaningful error association, visible focus, sufficient non-colour status communication and screen-reader announcements for state changes.
4. **Responsive resilience:** specify behaviour at 200% zoom and at a 320px viewport; the layout must not require horizontal scrolling.
5. **Content integrity:** use only supplied or clearly marked copy. If the value proposition, consent wording or privacy link is unknown, show its slot and identify what must supply it.
6. **Data minimisation:** request only the fields confirmed in `[FILL IN: signup fields]`. If personal data is involved, ask which regime governs it—GDPR, CCPA/CPRA or HIPAA—and leave the answer as `[FILL IN: governing data regime]` if unknown. Include retention period and deletion path in the design requirements, not in a comment.
7. **Dependency governance:** if an external component or service is proposed, leave its licence as `[FILL IN: dependency licence]` and state whether copyleft terms are acceptable as `[FILL IN: copyleft acceptability]`.

If the widget is embedded in a broader page, describe only the widget and its immediate integration boundary. Do not invent page sections, campaign claims or implementation metrics. Do not make performance claims unless measured evidence is provided.

## Output structure

Use the following four-part structure exactly:

1. **Screen list** — identify the widget’s placement context and responsive variants. Since only one widget is requested, describe one primary widget and any required viewport adaptations. Allocate approximately 10% of the response.
2. **Components per screen** — list the heading, supporting text, fields, consent area, submit control, status region and any optional elements. For each, state its purpose, required/optional status and content source. Mark unknown content with the relevant `[FILL IN: ...]` slot. Allocate approximately 35%.
3. **Behaviour per state** — define default, focus, invalid, loading, success, empty and error states. Specify keyboard sequence, validation timing, error text source, focus movement, screen-reader announcement and recovery action. Allocate approximately 40%.
4. **Design tokens** — provide token slots or confirmed values for colour, typography, spacing, borders, radius, focus indicator, control height, breakpoints and responsive rules. State contrast and focus requirements without inventing numeric values that were not supplied. Allocate approximately 15%.

Use tables for component inventories and state behaviour where they improve implementation clarity. Do not write production code. Include explicit questions for the unresolved blog identity, signup fields, integration, copy, audience and governing accessibility or data regimes.

## Style rules

Use a hybrid style: use concise tables and bullet lists for the screen, component, state and token specifications; use short narrative paragraphs only to explain design rationale, assumptions and conditional branches. Keep the register practical and implementation-facing. Avoid generic UI clichés such as “seamless experience,” “engaging users,” “clean and modern,” “frictionless signup,” and “best-in-class.” Replace them with observable behaviour or a marked input slot.

## Style rules (humanizer v1)

These govern every prose surface in the deliverable. Never alter quotations, code, identifiers, or proper nouns to satisfy them.

- Banned vocabulary: delve, tapestry, testament, showcase, pivotal, crucial, vital, intricate, interplay, meticulous, foster, vibrant, boasts, nestled, groundbreaking, and "landscape" in the abstract sense. Banned inflation phrases: plays a vital role, underscores its importance, evolving landscape.
- Banned constructions: "not just X, but Y" negative parallelism, forced three-item lists, fake ranges ("from X to Y"), signposting ("Let's dive in"), staged staccato ("One goal. Zero compromises."), and synonym cycling. Name a thing the same way every time.
- Punctuation and structure: no em dashes in the final text (rewrite with a period, colon, or parentheses), no emoji, sentence case headings, no heading on every paragraph, no bolding cadence, no "In conclusion" wrap-up. Close on a concrete fact.
- Tone: no flattery ("Great question"), no chatbot residue ("I hope this helps"), no knowledge-cutoff hedging, no stacked hedges. Hold the register the genre calls for and vary sentence length.
- Fact integrity: every instruction to be specific carries one boundary. Use only facts present in the user's input or in a verifiable source. Do not invent details to sound human. Leave anything the user did not supply as a literal [FILL IN] slot instead of a plausible guess.
- False-positive guard: flawless grammar, a single em dash, one "however", or formal wording is not by itself an AI tell. Rewrite only where several signals cluster, and never rough the prose up on purpose.

## Final self-audit

Draft the deliverable in full, then interrogate the draft on two counts. Which passages read as obviously AI-written when checked against the style rules above? Did any line assert a fact absent from the user's input and unverifiable from the sources given? Rewrite what fails and submit only the corrected version. The audit itself never appears in your output.

## Self-verification

1. Confirm that the deliverable is a newsletter signup widget specification, not a finished widget, marketing campaign, code sample or unrelated blog redesign.
2. Confirm that every component, state and token belongs to the widget’s requested scope.
3. Check that only the supplied fact—“newsletter signup widget for a blog”—is treated as confirmed.
4. Check that the blog name, brandAnchor, value proposition, signup fields, integration, consent text and privacy link remain slots unless provided.
5. Check that no arbitrary slot was filled with an invented blog name, benefit, field, service, colour, breakpoint or policy statement.
6. Check that the screen list, components per screen, behaviour per state and design tokens all appear in that order.
7. Check that loading, empty, error, success, invalid and default states are explicitly covered.
8. Check that keyboard operation, focus order, screen-reader labels and announcements are specified.
9. Check that WCAG 2.2 AA is named as the target and that ADA Title III or Section 508 is left for confirmation rather than assumed.
10. Check that 200% zoom and a 320px viewport are addressed without horizontal scrolling.
11. Check that any personal-data handling includes slots for the governing regime, retention period and deletion path.
12. Check that unsupported performance, compliance, privacy or conversion claims have not been presented as facts.
