# Cobalt Grid
> Electric cobalt italic serifs on a graph-paper canvas, anchored by stair-stepped pixel-glitch decorations and slim hairline rules.
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:** high
- **Density:** medium
- **Slides in demo:** 8
## Best for
Anything that should feel like a quietly serious design / research bulletin, art publication, or curated trend report. Strong for studio annuals, agency capabilities decks, design-research publications, architecture / art / academic decks, and any deck wanting one strict accent colour and a printed-ledger calmness rather than corporate polish.
## Avoid for
Decks that need warmth, multi-colour energy, or a casual / playful voice — the strict cobalt + cream + grid palette is intentionally austere.
## Workflow
1. **Clone `example.html`** into the user's workspace as the working file.
2. **Replace placeholder content** with the user's real headlines, body copy,
numbers, names, dates, and section labels. Match existing dimensions when
swapping image placeholders.
3. **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.
4. **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.
5. **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.
6. **Keep the navigation runtime as shipped.** If the deck ships an
`assets/deck-stage.js` or inline keyboard handler, leave it intact.
