What's inside
The instructions your model reads when the skill loads.
SKILL.md62 linessingle file
Mat
Dark sage canvas with bone paper and burnt-orange accent; mid-century modern with wood undertones.
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.
At a glance
Scheme: mixed
Formality: medium
Density: medium
Slides in demo: 9
Best for
Anything that should feel mid-century, tactile, and intentional: design studio credentials, architecture / interior brands, ceramics / craft / furniture, advisory decks. Also a warm, distinctive choice for tech, research, or business decks that want a considered analog feel instead of digital-cool.
Avoid for
Contexts that need fast tech energy or institutional restraint — the muted sage and burnt-orange palette is intentionally warm and slow.
Workflow
Clone example.html into the user's workspace as the working file.
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
than the demo holds, duplicate an existing slide of the most appropriate
layout. If less, drop slides from the bottom. Update page-number labels.
Designing missing layouts: if a slide needs a layout the template
doesn't have, design it from scratch using the same fonts, palette,
decorative vocabulary, spacing rhythm, and component grammar — never bail
to a different template.
