Prompt
Could you create an HTML slide deck for a grassroots environmental campaign pitch? We want to present our mission statement to local volunteers with an energetic, poster-style design that feels authentic, graphic, and urgent rather than corporate polish. Please provide the full HTML presentation inside an artifact element so that keyboard navigation works for stepping through our slides.

Activist poster energy: blue, orange, red on cream, with Alfa Slab + Caveat Brush.
A single self-contained HTML deck — typography, palette, decorative system,
and slide vocabulary are all tuned together. Mixing layouts across templates
breaks the system; stay inside this one.

Best for
Anything that should feel honest, loud, and graphic: cultural commentary, manifestos, civic and community decks, design talks, campaign pitches. Excellent for founder-vision moments, mission statements, or any deck — including across industries — that wants protest-poster energy instead of corporate polish.
Avoid for
Contexts where institutional restraint is the actual goal — the saturated political-poster palette commits hard to expressive energy.
Workflow
Clone example.html AND the assets/ folder into the user's workspace.
This template ships an assets/deck-stage.js runtime (keyboard navigation,
stage rendering); the HTML references it as assets/deck-stage.js, so the
file must sit next to the cloned HTML or that path will 404 in the generated
artifact and navigation will silently break. Inlining the JS into a single
<script> block in the HTML is an acceptable alternative when a single
self-contained file is preferred.
Replace placeholder content with the user's real headlines, body copy,
numbers, names, dates, and section labels. Match existing dimensions when
swapping image placeholders.
Preserve the design system. Never substitute fonts, recolor the palette,
restructure the layout grid, or strip decorative elements (corner brackets,
paper grain, geometric shapes, illustrated SVGs). They are part of the
identity.
Adjust deck length by duplicating layouts. If the user has more content
