Create an editable HTML presentation with a 16:9 canvas, previous/next buttons, arrow-key navigation, a slide counter and a one-slide-per-page print layout for [PROJECT] and [AUDIENCE]. The task is: Data Story Presentation.

## Required content and structure

Frame a question, show comparable values, explain uncertainty and recommend a decision.

Use [APPROVED_CONTENT] as the source of names, dates, figures, claims and destinations. List missing inputs before substituting anything. If a demonstration is needed, label its content as fictional. Do not invent customer quotes, rankings, partner logos or product capabilities.

## Design direction

Use [BRAND_RULES] and the design system already selected in the project. If no system is supplied, start with this direction: white, midnight navy and restrained blue; strong alignment and simple evidence diagrams. Keep type, spacing and color roles consistent. Prioritize the task over decorative elements and avoid a generic collection of unrelated cards.

## Content preparation

Frame one question and prepare the values, units, dates, sources and uncertainty needed to answer it. Decide which comparisons are valid before choosing chart types.

## Layout and behavior

Build a sequence in which each chart answers a specific part of the question. Use consistent scales and annotate the evidence that changes the interpretation.

## Task-specific acceptance check

- Keep axes, units, missing values and source dates visible.
- Inspect axes, missing values and denominators.
- A visually dramatic difference should remain proportionate to the actual data, and recommendations should acknowledge unresolved uncertainty.

## Implementation and review

Keep text editable. Use semantic structure, descriptive controls, visible keyboard focus and appropriate empty/error states. Check narrow and wide layouts. Respect reduced-motion preferences. Preserve any existing project framework and dependencies; do not silently replace the stack. Return the editable files and explain any incomplete behavior or unsupported inputs. Review this specific task before proposing extra features.

Keep one main idea per slide. Use charts only when actual comparable values are supplied; include units, source dates and limitations. Keep speaker notes separate from visible slide content.

## Reference attachment and reconstruction goal

Attach reference.webp from this prompt’s download bundle alongside this prompt in OpenDesign. Build an editable result with a similar composition and hierarchy; do not embed the whole reference image as the finished interface. Preserve approved project content and brand rules if they conflict with fictional sample labels. If the image is missing or unreadable, ask for it instead of claiming visual fidelity.

## Reference composition and content

Use the attached reference.webp as the visual reference for Data Story Presentation. Before building, identify the major regions from top to bottom, their relative widths and heights, alignment, spacing, typography hierarchy, surface colors, borders, imagery and repeated components. Preserve those relationships rather than substituting a generic template. Required task content: Frame a question, show comparable values, explain uncertainty and recommend a decision. Use the following task-specific layout guidance when translating the image into editable elements: Build a sequence in which each chart answers a specific part of the question. Use consistent scales and annotate the evidence that changes the interpretation.

## Visual direction from the example brief

white, midnight navy and restrained blue; strong alignment and simple evidence diagrams.

## Slide structure and presentation behavior

Recreate the slide composition as editable title, body, visual and annotation elements. A pictured slide is one view, not evidence of a complete deck. Use the supplied narrative to build any requested additional slides; preserve its typography, margins, color roles and alignment. Build a sequence in which each chart answers a specific part of the question. Use consistent scales and annotate the evidence that changes the interpretation. Keep navigation outside exported slide content. Keep axes, units, missing values and source dates visible.

## Visual comparison and delivery

1. Compare the result with the attached image at matching proportions. Review major region placement, relative image sizes, line breaks, spacing, typography hierarchy, contrast, active states and content density before polishing decorative details.
2. Then test the narrow layout without squeezing desktop text into tiny labels.
3. Keep logos, photos and icons as separate assets and all meaningful labels editable. List any unavailable fonts/assets and any intentional departures. Return the working files plus a concise account of implemented behavior and remaining integrations; do not promise a pixel-identical result from the prompt alone.

## Adapting the reference to slide dimensions

The attached visual reference is a 3:2 concept image, while the requested presentation uses 16:9 slides. Recompose its text, images, charts and spacing as separate editable elements on a 16:9 canvas. Do not stretch the reference or crop the whole composition to force a match. Preserve the hierarchy, keep the supplied content readable, and adapt each slide to its own message.
