The site is one page, and it argues one thing: a description is lowered through
representations until it is pixels, and the same work happens at every level.
Its five depths — source, compile, element, layout, raster — order everything
on it.

## Sections

- **Masthead** — "I take what you describe and lower it."
- **One expression, five representations** — the same declaration shown as
  source, compiled output, resolved elements, solved layout boxes and a raster,
  scrubbed through by depth.
- **The stack, as owned** — the published packages, ordered by the depth each
  occupies, with live npm download counts.
- **Built on it** — applications that use the stack, as evidence it is used.
- **What comes out** — a card rendered server-side by meo-canvas, the site's own
  renderer drawing the site's own content.
- **Ledger** — work and study as one dated index.
- **Colophon** — what the page is built with.

## Published packages

- **@meonode/ui** — React UI engine that creates web interfaces without JSX,
  using function-based composition. Type-safe UIs with CSS-first prop styling,
  and context-based theming with RSC support. TypeScript, React, Emotion.
  https://ui.meonode.com
- **@meonode/compiler** — SWC WASM plugin that rewrites @meonode/ui call sites
  into pre-partitioned marker props at build time, so the runtime skips
  static/dynamic prop classification on every render. Rust, SWC, WebAssembly.
  https://www.npmjs.com/package/@meonode/compiler
- **meo-canvas** — declarative scene trees compiled to image bytes: layout
  solved with Taffy, painted on Skia. One renderer behind both a Rust crate and
  a Node addon. v10 moved from Yoga to Taffy, giving flexbox, grid and block
  rather than flexbox alone. Rust, Skia, Taffy, Neon.
  https://l7aromeo.github.io/meo-canvas/
- **meo-skia-canvas** — Skia-backed HTML Canvas 2D API for Rust and Node, with
  GPU-accelerated, multi-threaded rendering. HDR and wide-gamut colour, PDF and
  SVG vector export, prebuilt binaries as optional platform packages. Rust,
  Skia, N-API. https://www.npmjs.com/package/meo-skia-canvas
- **meocord** — lightweight, extensible framework for building Discord bots with
  a decorator-based command architecture and CLI tooling. TypeScript,
  Discord.js. https://www.npmjs.com/package/meocord

## Applications

- **Chu Tao** — multi-service Discord bot across four live-service games
  (Genshin Impact, Honkai: Star Rail, Zenless Zone Zero, Neverness to
  Everness), built on the stack above: a discord.js bot, a Rust REST API on
  axum and SeaORM, and a Next.js portal for OAuth and account linking.
