"""Atman — Linguistic Demo · Gradio 6 theme.

Paste above build_ui() (or import: `from theme import theme`).
Pair with style.css via:

    with gr.Blocks(title="Atman Linguistic Demo", theme=theme, css=css) as demo:

IMPORTANT: also remove `theme=gr.themes.Soft()` from demo.launch() — it would
silently override this one.
