# Felhom design system v2
|
||
|
||
**Status:** canonical reference. Shipped in the controller UI with **TASK-D0** (controller v0.96.0,
|
||
2026-07-02); D1–D4 (settings IA split, Tárhely nav promotion, website, hub) build from this document.
|
||
|
||
The system was approved via two mockup rounds. Four pillars:
|
||
|
||
1. **Logo-derived navy palette** — a single blue accent on layered navy, replacing the GitHub-dark clone.
|
||
2. **Exception-based status color** — nominal state is blue/neutral; amber/red appear **only on deviation**.
|
||
3. **Vendored assets** — fonts and icons ship inside the binary; no CDN dependency (offline customer nodes).
|
||
4. **Flat metadata** — no pills, no shadows, no bubbles; one 2px radius everywhere.
|
||
|
||
## The rule set
|
||
|
||
- **One radius: 2px** (`--radius`). The only exceptions are true circles (state dots, spinners) at 50%.
|
||
- **No shadows.** No `box-shadow` anywhere. Depth comes from background layering (`--bg-0/1/2`) and
|
||
hairlines (`--line`, `--line-soft`).
|
||
- **Boxless sections.** Section headers are an h3 + muted hint over a 1px hairline (`.section-h`),
|
||
not a card. Panels (`.panel`) exist for genuinely grouped content, flat: bg-1 + 1px line.
|
||
- **Color = exception.** Anything operating normally is blue or neutral. Green does not exist in the
|
||
system. Amber (`--warn`) and red (`--crit`) are reserved for deviations that need attention.
|
||
Categorical **data series** (charts) are exempt — they may use distinct hues; *status* may not.
|
||
|
||
## Tokens (canonical, verbatim)
|
||
|
||
```css
|
||
:root {
|
||
--bg-0: #0A1220; --bg-1: #0F1B2E; --bg-2: #16263F;
|
||
--line: #22344F; --line-soft: #1A2A42;
|
||
--text-1: #EDF2F9; --text-2: #94A6BF; --text-3: #5E7392;
|
||
--blue: #0083D8; --blue-bright: #2EA8F5; --blue-dim: rgba(0,131,216,.13);
|
||
--warn: #E0A93E; --warn-dim: rgba(224,169,62,.12);
|
||
--crit: #E5534B; --crit-dim: rgba(229,83,75,.12);
|
||
--radius: 2px;
|
||
--font-ui: 'Plus Jakarta Sans', -apple-system, sans-serif;
|
||
--font-data: 'JetBrains Mono', monospace;
|
||
}
|
||
```
|
||
|
||
Semantics: `--bg-0` page, `--bg-1` panel, `--bg-2` elevated/nested surface (buttons, inputs, table
|
||
stripes). `--text-1` primary, `--text-2` secondary, `--text-3` muted/labels. `--line` visible
|
||
hairline, `--line-soft` row separators and meter tracks. `--blue` fills and primary actions,
|
||
`--blue-bright` text-on-dark accent and hover, `--blue-dim` selection/hover washes.
|
||
|
||
## Typography
|
||
|
||
- **UI face:** Plus Jakarta Sans (weights 400–800). **Data face:** JetBrains Mono (400–500) for
|
||
every numeric/technical value: sizes, times, percentages, paths, IDs, versions.
|
||
- Both are **vendored variable woff2 files** embedded in the binary and served from
|
||
`/static/fonts/` (immutable cache). **latin-ext is mandatory** — Hungarian ő/ű break without it.
|
||
`unicode-range` is preserved from the upstream subsets so latin-ext only loads when needed.
|
||
- No CDN font loading anywhere. `fonts.googleapis.com` is a banned string in the codebase.
|
||
|
||
## Iconography
|
||
|
||
- **Vendored Lucide sprite** (`templates/icons.html`, 30 icons as `<symbol id="i-<name>">`),
|
||
included once at the top of `<body>`. Stroke = `currentColor`, stroke-width 2, round caps.
|
||
- Usage convention everywhere: `<svg class="ico"><use href="#i-hard-drive"/></svg>`
|
||
(`.ico` 16px, `.ico-sm` 14px, `.ico-spin` for progress).
|
||
- **Emoji are banned** in templates and JS-built strings (✅❌⚠🔒⏳… — see the D0 grep gate list).
|
||
- Standalone pages that don't include the layout (catchall, setup wizard) get inline SVGs or plain
|
||
text, not the sprite.
|
||
|
||
## Components
|
||
|
||
### Meter (`.meter` + `.meter-track` / `.meter-fill`)
|
||
The capacity readout — replaces every zone-colored bar. A 3px hairline track (`--line-soft`) with a
|
||
fill; **the fill is blue in nominal state**. Two 1px *neutral* ticks are baked into the track at 70%
|
||
and 85% (`.meter-track::before/::after`; `.no-ticks` disables). The wrapper carries the state class
|
||
from `usageColor`: `nominal` (blue), `warn` (amber fill), `crit` (red fill). Under warn/crit a
|
||
`.meter-flag` renders (dim background chip + triangle-alert icon) with the exact copy:
|
||
warn → **„Fogyóban a hely"**, crit → **„Kritikusan kevés hely"** (storage meters).
|
||
Disconnected/unknown: `.meter-empty` — empty track, value `—`, no color, no flag.
|
||
Deploy-page variant `.meter-track-stacked`: two segments — committed = solid `--blue`, planned/new =
|
||
`--blue` at 35% opacity.
|
||
|
||
### Tag (`.tag`)
|
||
The state chip — replaces pills. Inline-flex, **2px radius**, 1px border, 6px round dot. Modifiers:
|
||
`tag-run` (blue border/text/dot), `tag-progress` (blue + pulsing dot; `prefers-reduced-motion`
|
||
respected), `tag-warn` (amber + dim bg), `tag-crit` (red + dim bg), `tag-neutral`/`tag-off`
|
||
(gray, hollow dot). Protected/locked content uses a neutral tag with the `i-lock` icon.
|
||
|
||
### Metadata row (`.metarow` / `.metarows`)
|
||
Informational chips ("~512M", "Pi kompatibilis", "HDD szükséges") become icon + text with **no
|
||
container**: 14px muted-stroke icon, `--text-2` text, mono for values.
|
||
|
||
### Panel / List (`.panel`, `.list .row`, `.stack-list`)
|
||
Panel: `--bg-1`, 1px `--line`, 2px radius, no shadow. List: one panel whose rows are separated by
|
||
`border-top: 1px solid var(--line-soft)`; each row has a 2px left state edge via `::before` —
|
||
blue for run/progress, amber for warn, transparent for neutral/off.
|
||
|
||
### Section header (`.section-h`)
|
||
h3 + right-aligned muted hint over `border-bottom: 1px solid var(--line)`. No box.
|
||
|
||
### Stats (`.stats-grid` / `.stat-card`)
|
||
Boxless figures with 1px right hairline dividers; numbers in `--font-data` at 1.9rem. A zero
|
||
"Leállítva" renders `--text-3` (`.stat-zero`); a nonzero stopped count renders `--warn`
|
||
(`.stat-warn`) — the exception rule applied to numbers.
|
||
|
||
### Buttons
|
||
2px radius. Default: `--bg-2` + `--line` border, hover border `--blue`. `.btn-primary`: solid blue.
|
||
`.btn-danger`: **transparent background, `--crit` border + text** — danger is outline until the
|
||
confirm step (filled red only inside confirmation modals). `:focus-visible` = 2px `--blue-bright`
|
||
outline on all interactive elements.
|
||
|
||
## State truth tables (funcmap, controller `internal/web/funcmap.go`)
|
||
|
||
`stateColor(ContainerState)` → class suffix (consumed as `tag-*`, `stack-state-*`, `state-text-*`):
|
||
|
||
| ContainerState | token | rendering |
|
||
|---|---|---|
|
||
| running | `run` | blue tag + blue row edge — nominal |
|
||
| starting, deploying | `progress` | blue tag, pulsing dot, blue edge |
|
||
| unhealthy | `warn` | amber tag + amber edge |
|
||
| restarting | `warn` | amber (a restart loop is a problem, not progress) |
|
||
| stopped, exited | `neutral` | gray tag, hollow dot, **no** colored edge |
|
||
| paused | `neutral` | gray |
|
||
| not_deployed, unknown | `off` | gray tag, no row edge |
|
||
|
||
> Deliberate semantic change (operator-approved): **stopped/exited is neutral, not red.** A
|
||
> customer-stopped app is not an emergency; genuine failures surface via unhealthy state + alerts.
|
||
|
||
`usageColor(percent)`: `<70 → nominal`, `70–85 → warn`, `≥85 → crit`.
|
||
`tempColor(celsius)`: `>75 → crit`, `≥60 → warn`, else `nominal` (thresholds unchanged from v1).
|
||
Hungarian `stateLabel` copy is frozen (guarded byte-identical by unit test).
|
||
|
||
Text color classes: `.state-text-{run,progress,warn,crit,neutral,off,nominal}` —
|
||
`nominal` = `--text-1` (no color), `run`/`progress` = `--blue-bright`, `neutral`/`off` = `--text-3`.
|
||
|
||
## Chart palette (Chart.js, monitoring)
|
||
|
||
Categorical series (data, not status): cpu `#2EA8F5`, memory `#8E7CE8`, temp `#E0A93E`,
|
||
load `#5EC4B6`. Chrome: tooltip bg `#0F1B2E`, title `#EDF2F9`, body `#94A6BF`, border `#22344F`,
|
||
ticks `#94A6BF`, axis titles `#5E7392`, grid `rgba(34,52,79,.5)`.
|
||
|
||
## Enforcement
|
||
|
||
The D0 grep gate (all counts must be 0 in `controller/internal/{web,setup}`):
|
||
`fonts.googleapis.com`, `border-radius: 999px`, `box-shadow`, the GitHub-dark hexes
|
||
(`#0d1117 #161b22 #1c2128 #30363d #238636 #da3633 #d29922 #db6d28`),
|
||
`system-bar-{green,yellow,red}`, `state-text-{green,red,yellow,orange}`, and the emoji list
|
||
