I need a 4-slide HTML deck showcasing my holistic wellness retreat program, 'Solstice Healing'. The slides need to cover retreat locations, daily schedules, guest testimonials, and booking packages. Output the deck inside an artifact with identifier 'zhangzara-capsule' and title 'Solstice Healing Retreat'.

Capsule
Modular pill-shaped cards on warm bone with a full pastel-pop palette.
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: light
Formality: medium-low
Density: medium
Slides in demo: 10
Best for
Anything that should feel modular, modern, and a little Y2K: lifestyle brands, creator portfolios, DTC launches, beauty / wellness, agency credentials. Also fun for a playful tech demo or a research deck that wants pop-art clarity instead of gravitas.
Avoid for
Contexts that require traditional institutional weight — the capsule shapes and pastel pops actively soften authority.
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.
