Gandalf Design System

01 · Foundations

A gate, not a trading floor.

Gandalf’s source avoids the visual noise of generic crypto products. It uses dense but calm surfaces, serif moments for identity and value, monospace for addresses and hashes, and color chiefly for action, ledger identity, and explicit state.

Sealed by default

Security is a visible boundary

Passwords appear at the signing edge, secret warnings are direct, and the header continuously says “sealed.”

Extracted

Warm restraint

Gold guides; it does not decorate

Gold marks the sigil, primary action, focus, selection, and high-value identity cues.

Extracted

Technical honesty

Show the transaction machinery

Inputs, outputs, fees, network, destination, hashes, reservations, and node reasons remain inspectable.

Extracted

Do

Use warm neutrals, compact hierarchy, explicit state labels, and plain security language. Keep addresses, amounts, and hashes stable with monospace or tabular numerals.

Don’t

Add neon gradients, speculative market imagery, anonymous “web3” styling, or color-only status. Avoid making a dangerous action look routine.

One system, two compositions

Unified contract

Theme and density are independent axes. Light and dark change semantic color; comfortable and compact change rhythm, padding, and information density. Components, states, accessibility rules, and token names remain the same.

Comfortable · websitePage recipe

Clear public narrative

Explain the value before the machinery.

Use generous rhythm, readable line length, proof-oriented cards, and one obvious next action.

Compact · applicationFixed-shell recipe

The repository supplies paired values, not mathematically generated scales. The primitive layer therefore keeps named pairs rather than inventing numbered ramps.

Ledger and avatar identity

Ledger colors are semantic identities, not product status. The five avatar colors come from the local DiceBear generator and never leave the device.

Gandalf is generic; this recipe shows its source product application. The patterns are limited to journeys implemented in the repository: account selection, synchronization, receive, UTXO visibility, compose/review/sign/result, status tracking, setup/import, password unsealing, and encrypted backup.

Rejected

Quote the node reason, release inputs, and provide edit-and-retry.

Security boundary rule. Secrets shall not pass into logs, remote assets, analytics, clipboard persistence, or decorative UI. Gandalf’s source keeps signing in WASM, displays “sealed” in the header, generates avatars locally, and exports only re-encrypted vault material.

05 · Implementation guidance

Portable by purpose, not by page.

Import the CSS, set one theme attribute at the application root, and consume semantic or component tokens. Primitive values are for theme definitions and auditing—not routine component authoring.

1 · Download two files

Consume tokens, not colors

.account-summary {

  border: var(--border-thin)
          solid var(--card-border);
  border-radius: var(--radius-card);

.account-summary__action {
  color: var(--button-primary-ink);
  background: var(--button-primary-bg);
}

Apply a theme

<html>...</html> <!-- light root -->
<html data-theme="dark">...</html>

// System preference
const dark = matchMedia(
  '(prefers-color-scheme: dark)'
).matches
document.documentElement.dataset.theme =
  dark ? 'dark' : 'light'

Integration sequence

Copy the CSS into the consuming application or package it unchanged.
Alias product primitives into a shared namespace only at the theme boundary.
Build shared components against semantic and component tokens.
Keep ledger identity tokens separate from status tokens.
Run contrast and keyboard tests after any downstream token remapping.

Cloudflare Pages deployment

Static deployment recipe

This direct-upload approach needs no build output or large media pipeline. Keep both named files available for downloads and publish a copy of the reference as index.html.

deploy_dir="$(mktemp -d)"
cp index.html "$deploy_dir/index.html"
cp gandalf-design-system.css "$deploy_dir/gandalf-design-system.css"

npx --yes wrangler pages deploy "$deploy_dir" \
  --project-name=gandalf-system \
  --branch=main \
  --commit-dirty=true

First deploy

Pages project

Wrangler creates or updates the static project and provides a public pages.dev address.

After domain purchase

Attach gandalfsystem.com

Add the apex domain and optional www domain under Cloudflare Pages → Custom domains.

Public CSS

Use anywhere

Once deployed, applications can link to https://YOUR-DOMAIN/gandalf-design-system.css.

Ready, not deployed. The Pages project is named gandalf-system; attach gandalfsystem.com after registration and the first deployment.

Merge with another system without coupling

Share contracts

Agree on semantic contracts such as canvas, surface, text, border, action, status, focus, and control geometry. Let each product map its own primitives into those contracts.

Avoid selector inheritance

Do not exchange page-specific classes between products. Shared packages should expose tokens and low-level components, never selectors named after one route, screen, or application.

/* Shared contract */
--shared-color-surface: var(--color-surface);
--shared-color-action-primary: var(--color-action-primary);
--shared-control-radius: var(--radius-control);

/* Gandalf keeps product identity */
--shared-network-primary: var(--color-ledger-primary);
--shared-security-boundary: var(--security-border);

Evidence classification

Extracted Colors, type, spacing, radii, borders, popup shell, fields, buttons, cards, rows, status, setup, receive, send, signing, and security language.

Derived Secondary text, subtle/strong borders, semantic selection, and explicit elevation levels needed for a complete portable layer.

A11y fix 44px targets, light ledger glyph ink, and dark danger-toast ink.

Recommended Tabs, breadcrumbs, pagination, switch, tooltip, skeleton, table, dropdown, dialog, desktop sidebar, and mobile nav.

Known ambiguity. The repository references design-018, but that document and product screenshots are not present in this repository. The implementation itself is therefore the governing evidence. Cardano, XRPL, and Stellar have catalog colors but no live adapter screens yet.
