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

numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders.

  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,

restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity.

  1. Preserve the design system. Never substitute fonts, recolor the palette,

than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels.

  1. Adjust deck length by duplicating layouts. If the user has more content

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.

  1. Designing missing layouts: if a slide needs a layout the template

assets/deck-stage.js or inline keyboard handler, leave it intact.

  1. Keep the navigation runtime as shipped. If the deck ships an
