"""Brutalist Mono — pure black/white, no color accent.

Palette tokens are the source of truth; CSS pulls from them. The audio
waveform is the only optionally-colored element (rendered white in v1).

UI architecture (locked):
- Sidebar layout (NOT ``gr.Tabs``) per wireframes at
  ``docs/superpowers/specs/mockups/``.
- ``.ams-sidebar`` is a flex column at desktop, fixed-width 170-190 px.
- ``.ams-side-radio`` is the mode-nav: a ``gr.Radio`` re-skinned via CSS
  so each option renders as a full-width sidebar pill. The native
  ``:checked`` pseudo-class supplies the "active" highlight.
- ``.ams-content`` is the right column containing 5 ``.ams-tab-pane``
  groups; one is visible at a time.
- Media queries: at ``<= 1024 px`` the sidebar shrinks to an icon rail.
  At ``<= 640 px`` the sidebar is replaced by a horizontal scroll strip
  at the top.
