ci / rust (push) Successful in 2m40s
Rewrites CLAUDE.md as the current-architecture reference, drops the registry from INSTALL/PRODUCT/DESIGN and the web README, deletes the registry Dockerfile, and marks the dated design specs superseded where they describe the registry, JWT auth, or cross-host attach. The installer loses its configure step — every config field now has a default, so a daemon starts with no config file at all.

# Design
|
||
|
||
Visual system for the Maestro web UI. Source of truth is
|
||
`web/src/styles.css` (`:root` token block); this document mirrors it. Register:
|
||
**product** — design serves the task. See [PRODUCT.md](PRODUCT.md) for strategy.
|
||
|
||
## Theme
|
||
|
||
Dark is the default (terminal context); light is a full peer. Everything is
|
||
driven by CSS custom-property tokens, so a theme is a token swap, never a
|
||
restyle. Resolution order:
|
||
|
||
1. `:root[data-theme="light"|"dark"]` — explicit user pin (persisted in
|
||
`localStorage` as `maestro-theme`), set by the header toggle.
|
||
2. `@media (prefers-color-scheme: light)` — followed when the user hasn't
|
||
pinned a theme.
|
||
3. Otherwise the `:root` defaults (dark).
|
||
|
||
The xterm terminal stays dark in both themes by convention; `--term-bg` is dark
|
||
in light mode too.
|
||
|
||
## Color (OKLCH)
|
||
|
||
Strategy: **Restrained** (product floor) with one committed signal hue —
|
||
**green = "alive"**, carrying running status, primary action, focus, and
|
||
selection. Neutrals are a cool slate (hue ~256). Green is the signal, never a
|
||
costume: text stays neutral high-contrast, surfaces stay slate, so the result
|
||
reads terminal-native without CRT novelty.
|
||
|
||
| Role | Dark | Light |
|
||
|---|---|---|
|
||
| `--bg` | `oklch(0.178 0.012 256)` | `oklch(0.985 0.003 256)` |
|
||
| `--surface` | `oklch(0.214 0.014 256)` | `oklch(1 0 0)` |
|
||
| `--surface-2` | `oklch(0.252 0.016 256)` | `oklch(0.965 0.004 256)` |
|
||
| `--surface-3` | `oklch(0.292 0.018 256)` | `oklch(0.93 0.006 256)` |
|
||
| `--border` | `oklch(0.318 0.018 256)` | `oklch(0.892 0.008 256)` |
|
||
| `--border-strong` | `oklch(0.4 0.022 256)` | `oklch(0.82 0.012 256)` |
|
||
| `--ink` (body text) | `oklch(0.945 0.006 256)` | `oklch(0.26 0.014 256)` |
|
||
| `--muted` (secondary) | `oklch(0.722 0.014 256)` | `oklch(0.47 0.016 256)` |
|
||
| `--faint` (tertiary/decorative) | `oklch(0.58 0.014 256)` | `oklch(0.62 0.016 256)` |
|
||
| `--accent` / `--live` | `oklch(0.83–0.84 0.16–0.17 152)` | `oklch(0.6 0.15–0.16 151)` |
|
||
| `--accent-ink` (text on accent) | `oklch(0.2 0.03 256)` | `oklch(0.99 0.01 152)` |
|
||
| `--danger` | `oklch(0.72 0.18 25)` | `oklch(0.55 0.21 27)` |
|
||
| `--warn` | `oklch(0.82 0.14 85)` | `oklch(0.66 0.15 75)` |
|
||
|
||
Body and secondary text meet WCAG AA (≥4.5:1) against their surface in both
|
||
themes; `--faint` is reserved for decorative/large use only. Status never relies
|
||
on color alone — a running dot pulses and is filled; a dead session is a hollow
|
||
ring **and** carries an "exited" badge.
|
||
|
||
Tints/glow derive from the accent at low alpha: `--accent-tint` (0.12),
|
||
`--accent-ring` (focus, ~0.55), `--live-glow` (status halo).
|
||
|
||
## Typography
|
||
|
||
**Monospace is the UI typeface** (brand identity), system-stack only (offline-
|
||
safe, zero web-font dependency, embedded clean into the web binary):
|
||
|
||
- `--font-mono`: `ui-monospace, "SF Mono", "Cascadia Code", "JetBrains Mono", "Roboto Mono", Menlo, Consolas, monospace` — chrome, labels, data, ids, the wordmark.
|
||
- `--font-sans`: `system-ui` stack — reserved for the few prose strings (empty-state sentences).
|
||
|
||
Fixed rem scale (product register; not fluid/clamped): `--fs-11` 0.6875rem
|
||
through `--fs-20` 1.25rem, in ~1.12–1.2 steps. Base body `--fs-15` (0.9375rem),
|
||
line-height 1.45. No display sizes — the largest type is the 1.25rem wordmark.
|
||
|
||
## Spacing, radius, sizing
|
||
|
||
- Spacing scale: `--sp-1`..`--sp-8` = 4 / 8 / 12 / 16 / 20 / 24 / 32 px.
|
||
- Radius: `--r-1` 6 · `--r-2` 9 · `--r-3` 14 · `--r-pill` 999.
|
||
- Touch/row sizing: `--row-h` 46, `--control-h` 38, `--tap` 40 (mobile-first
|
||
touch targets).
|
||
|
||
## Motion
|
||
|
||
State and feedback only; 120–240 ms, ease-out (`cubic-bezier(0.22,1,0.36,1)`),
|
||
no bounce. Tokens `--dur-fast`/`--dur`/`--dur-slow`.
|
||
|
||
- Living signals: brand dot + running-status ripple pulse (the "alive" cue);
|
||
`connecting` state pill pulses.
|
||
- Interaction: row hover/focus, button press (1px), input focus ring, chevron
|
||
rotation, theme-toggle sun/moon swap.
|
||
- Modal: bottom-sheet slide-up on mobile, scale-pop on ≥600px.
|
||
- Every animation has a `prefers-reduced-motion: reduce` path (pulses off,
|
||
transitions near-instant).
|
||
|
||
## Layout & structure
|
||
|
||
Mobile-first, structural responsiveness (not fluid type). Single `≤520px`
|
||
breakpoint stacks the header (full-width search, wrapped actions). `≥600px`
|
||
switches the spawn modal from bottom-sheet to centered dialog. A faint slate grid texture sits on `--bg` as
|
||
terminal atmosphere (very low contrast, not decoration).
|
||
|
||
## Components
|
||
|
||
Three surfaces, all DOM built in TS, styled by class:
|
||
|
||
- **Catalog** — sticky blurred header (pulsing wordmark, search, theme toggle,
|
||
Spawn); status bar (`N sessions · M live` tally); session tree (collapsible
|
||
directory folders with counts, leaf rows with status dot, name, command meta,
|
||
exited badge, reveal-on-hover kill). Empty states are distinct and teach:
|
||
no-sessions, no-search-match.
|
||
- **Attach** — header (back, `session <id>`, live/closed/error state pill) over
|
||
a framed dark xterm with a green cursor.
|
||
- **Spawn modal** — bottom-sheet/dialog form; mono inputs with green focus
|
||
ring; grouped worktree fieldset.
|
||
|
||
Interactive elements ship default / hover / focus-visible / active / disabled
|
||
states; the accent green is used only for action, selection, focus, and live
|
||
status — never decoration.
|
||
|
||
## Dev review aids (DEV-only, stripped from production)
|
||
|
||
`web/src/mock.ts` + query params seed a representative catalog without a running
|
||
daemon: `?mock` (seed sessions), `?mock&spawn` (open the spawn modal),
|
||
`?theme=light|dark` (pin a theme). Guarded by `import.meta.env.DEV`.
