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

The aesthetic identity of ACE Music Studio: precision, density, mono-
spaced labels, true neutral grays, and a single white accent rationed
across active states + the primary CTA. Inspired by record-sleeve
liner notes and a code editor's chrome.

Typography (selected per the frontend-design discipline):
- IBM Plex Sans  — body, brand, helper text. Mechanically refined,
  warmer than Inter, free via Google Fonts.
- IBM Plex Mono  — labels, status indicator, brand period, metadata
  JSON, all-caps small text. Distinctive character without going
  novelty.

The wireframes at ``docs/superpowers/specs/mockups/`` remain the visual
source of truth. The mobile breakpoint at 640 px replaces the sidebar
with a horizontal scroll strip and crushes the outer Gradio padding so
the full 360 px viewport is actually usable.
