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.

# 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.
