Introduction

What Appsudo is
- Appsudo is a lightweight cross-platform framework for building mini apps.
- Logic is written in Python.
- UI is described in ASXML, an XML-like view language.
- Styling is applied inline or through ASCSS files.

Core mental model
- An app is a Python class that subclasses `App`.
- The docs use `ViewInflater` to inflate views from files in `view/`.
- The docs recommend a `self.data` object for UI state in Appsudo UI apps.
- ASXML binds to that state with expressions like `{data.title}`.
- Components are a mix of containers, form inputs, media surfaces, and control primitives.

What the docs emphasize
- Write-once, cross-platform UI composition.
- Declarative layout plus imperative Python callbacks.
- A relatively rich built-in component catalog.
- Special support for three app shapes:
  normal ASXML apps, reusable custom components, and game/HTML mini apps.

Practical references surfaced elsewhere in the docs
- `App` is the base class for apps.
- `ViewInflater` is used in the examples and structure walkthrough to inflate ASXML views.
- `self.data` plus `{data.field}` bindings are the recommended pattern for UI apps.
