Replaces the conventional chat aesthetic on /ai with a brutalist-mono
operator deck. The page now reads as a flight recorder — turn numbers
in the gutter, hairline rules, sodium-amber phosphor primary on
deep-ink ground, vim-style modeline at the foot.
Type system is the design's load-bearing element:
- JetBrains Mono for everything system-y (operator lines, signatures,
modeline, session ids, tool calls)
- Newsreader serif for the agent's prose only — the synthesis voice
literally lifts off the page in a different family from the machine
voice. Operator and agent are typographically inseparable from their
speaker.
Layout changes:
- Sticky session header with a giant base36 session id ("3K9P · A4C2")
and a metadata strip showing agent, model, turn count, status. The
status pill flips colour: AMBER on stream, ROSE on awaiting confirm,
MINT on ready, MUTED on mock.
- Empty state is no longer the apologetic "How can I help you today?".
It's "ATLAS. standing by." in oversize mono with the agent name in
italic serif amber, a hairline divider, and a single one-liner
instruction prefixed with ›. Lines stagger in via animation-delay.
- Operator turns: monospace, 14px, sodium-amber › prompt, no bubble.
Hangs from a left gutter with T01/T02… turn number + UTC timestamp.
- Agent turns: serif, 17px/1.55, with a tiny mono signature underneath
("atlas» 03:14:08Z · recv"). Cyan accent column instead of amber.
- Composer: terminal frame (square, 1px border, focus ring is amber
glow). Internal ›_ prompt mark in front of the textarea, mono input.
- Bottom modeline: utc clock + turn count + estimated tokens on the
left, keyboard hints on the right. Streaming flips the right side
to a pulsing phosphor bar + STREAM label.
Atmosphere details:
- 2px scanline overlay (very faint, 1.2% opacity)
- Corner phosphor blooms (amber top-right, cyan bottom-left)
- Inline SVG turbulence grain (3.5% opacity) over the whole theme
- Cursor blink animation on the prompt mark
- Consolas-tier ligatures on the mono via JetBrains Mono ss01/calt
All theming scoped via [data-theme="console"] — picks up automatically
because /ai's AppShell now passes theme="console". Other routes are
untouched. Tool-call cards from @crema/agent-ui inherit the palette
via overridden CSS variables (--card, --border, --primary, etc) plus
a [data-slot="tool-call-card"] override for the frame.
