Design System / 07.13
Sections
Composed sections for product pages: demonstrations, comparisons, estimators, procedures, pricing, stories, and page-level navigation.
Announcement bar
A thin, optionally linked strip with a 44px dismiss control. With a storage key it applies a persisted dismissal after hydration; the server still renders the message so no-script readers retain it. Executable or blank link values fall back to plain text.

Inputs, types, and behavior
- Inputchildren / href
- TypeReactNode / string?
- BehaviorVisible message and optional safe link. Blank content omits the bar.
- Inputdismissible / storageKey
- Typeboolean / string?
- BehaviorDismissible by default; a key makes dismissal best-effort persistent in localStorage.
- Inputalign / external
- Type"center" | "start" / boolean
- BehaviorExternal links open in a new tab with noopener noreferrer.
- InputclassName
- Typestring?
- BehaviorMerged last on the full-width strip.
Case study section
A project-scale outcome story with a thesis, quotation, attribution, media, and up to four sourced metrics. Unlike Testimonial, it owns the section spacing and reading order. The host supplies every number and endorsement.

CTA section
A closing prompt with optional eyebrow, supporting copy, and action slot. Its sanctioned inverted register remains static; supplied controls still self-dim. Choose the root and heading level to match the surrounding document outline.

Component composition checklist
The identity article records the visual decisions behind the component rules.
API reference
Inputs, types, and behavior

- InputclassName
- Typestring?
- BehaviorMerged last on the semantic root.
Ecosystem section
A named matrix for products, integrations, or system primitives. It adds a role, description, metadata, and optional safe navigation to the static logo-wall idea. Shared seams preserve one field; linked marks and names self-dim without lowering explanatory copy.

Estimator section
A page-scale workspace for cost, capacity, ROI, or configuration tools. Inputs stay first in source order; estimate and breakdown form an attached results panel. The component performs no calculation and makes no pricing claim—the host owns state, arithmetic, and live announcements.

FAQ
A semantic question set built on Accordion. Invalid entries are omitted without discarding valid siblings, and separate heading props keep the section label and question buttons in a correct outline. A static no-script rendering keeps every answer available.

Mode showcase section
A horizontal tab set bound to one demonstration field. Each mode has its own title, explanation, metadata, and content, not just a changed illustration. Arrow, Home, and End keys follow the familiar tab model; the incoming panel settles by four pixels over 280ms and reduced motion renders it at rest.

Newsletter section
A controlled email form that presents idle, loading, error, and success states while leaving every request to the host. Success is announced and receives focus after submission. The specimen sends or stores nothing; its state buttons are local controls. Before hydration or without host behavior, the form is truthfully disabled.

Pricing card
One standalone comparison column. A featured state adds only a hairline badge; it does not lift, thicken, glow, or change the card geometry. This neutral specimen demonstrates structure and is not a published vvver offer.

Contrast, focus, semantics, and reduced motion are visual decisions.
