Website design:
- Translucent black (#0a0a0a) with gold (#d4af37) accents
- Strong serif typography (Playfair Display, Source Serif Pro)
- Glass-morphism cards with gold borders
- Responsive layout with elegant animations
Content:
- Landing page with hero, code demo, value props, benchmarks
- Effects-focused messaging ("No surprises. No hidden side effects.")
- Performance benchmarks showing Lux matches C
- Quick start guide
Technical:
- Added HTML rendering functions to stdlib/html.lux
- Created Lux-based site generator (blocked by module import issues)
- Documented Lux weaknesses discovered during development:
- Module import system not working
- FileSystem effect incomplete
- No template string support
The landing page HTML/CSS is complete and viewable.

// Html Module - DSL for building HTML/DOM structures

// compiled to efficient JavaScript for browser rendering.

|

// Example usage:
|
|
// let myView = div([class("container")], [
|
|
// h1([id("title")], [text("Hello!")]),
|
|
// button([onClick(Increment)], [text("+")])
|
|
// ])

|
|
// Parameterized by Msg - the type of messages emitted by event handlers
