Ledger

The public website for QuantSingularity.

  

Ledger is a searchable, self-contained index of every repository across the organization, styled after a trading blotter rather than a typical landing page: a live ticker tape, a grep-style filterable table, and a manifest of the engineering principles the org holds its projects to.

---

What it is

A single static HTML file. No build step, no framework, no dependencies beyond two Google Fonts. It is meant to be easy to read, easy to fork, and easy to keep in sync with the org's actual repository list.

Sections:

Section	What it does
Ticker	A continuously scrolling tape of every repo name and its primary language, paused on hover
Hero	Mission statement and live counts (repositories, domains, languages, principles)
What We Build / Engineering Principles	A two-panel manifest, styled as a code comment block and a set of assert statements
The Index	The core of the site: a grep-style search bar, domain filter chips, and a table of every repo with inline match highlighting and a live result count
Contribute	The org's contribution steps and a collaboration contact link

Tech stack

Layer	Choice
Markup, styling, behavior	Vanilla HTML, CSS, and JavaScript (no build tools, no package manager)
Typography	JetBrains Mono and IBM Plex Sans via Google Fonts
Data	Repository data is embedded directly in the page as a JavaScript array, no external API or database

Updating the repository index

The table on the site is generated from a single JavaScript array near the bottom of index.html:

const REPOS = [
  { name: "...", url: "...", desc: "...", lang: "...", domain: "..." },
  ...
];

To add, remove, or correct a project, edit this array directly. domain must match one of the six category codes used by the filter chips:

Code	Filter chip label
FULLSTACK.APPS	Fullstack Apps
INFRA.CORE	Platform Infra
AGENTS.MULTI	Multi-Agent AI
RESEARCH.DL	Deep Learning
LIBS.ENGINES	Libraries & Engines
RESEARCH.NB	Notebooks

No other part of the page needs to change. The ticker, table, counts, and filters all render from this one array.

Deployment

This repo is deployed via GitHub Pages as a project site. Any push to the default branch that touches index.html is picked up automatically once Pages is enabled in Settings → Pages.

Design notes

The palette and type system are defined as CSS custom properties at the top of index.html:

Token	Value	Use
--bg	#0A0D12	Base background
--amber	#E8A33D	Primary accent
--teal	#4FD1AE	Secondary accent (C++ tag, positive states)
--rose	#E1667C	Tertiary accent (Java tag)
--mono	JetBrains Mono	Headings, data, code
--sans	IBM Plex Sans	Body copy

Keep new UI within this token set rather than introducing new one-off colors. That is what keeps the site looking like one coherent system rather than a stack of separately designed sections.
