# Design System - Playzer

## Direction

**Feel:** Technical but warm. Like a well-organized sports facility — functional, clean, but with life. Not cold like a trading terminal, not playful like a toy app.

**Users:** Owners and employees managing sports complex bookings. They're juggling schedules, phone calls, and walk-ins. The interface should stay out of the way while they're working.

---

## Domain

**Concepts:**
- Turno (booking slot) — A scheduled time block
- Cancha (court) — Sports court/pitch
- Horario — Time slot
- Complex — The sports facility
- Estado — Booking status (confirmed, cancelled, etc.)

**Color world:**
- Court green (grass/tennis)
- Clay tan (paddle court)
- Pool blue (swimming)
- Wood grain (locker rooms)
- Concrete gray (tech floor)

**Signature:**
- Status pills use subtle borders + background tint, not bold badges
- Status communicates without demanding attention — whisper-level hierarchy

---

## Decisions

### Depth
**Approach:** Borders-only with surface elevation shifts
- No drop shadows
- Higher elevation = slightly lighter surface (in dark: lighter = higher)
- Subtle rgba borders define edges quietly

### Spacing
**Base unit:** 4px
- Micro: 2-4px (icon gaps)
- Component: 8-12px (inside buttons, badges)
- Section: 16-24px (between groups)
- Major: 32-40px (between distinct areas)

### Typography
**Font:** Geist Variable
**Scale:**
- Display: 28px / semibold / -0.02em tracking
- Heading: 20px / semibold / -0.01em tracking
- Body: 14px / normal / 0 tracking
- Label: 12px / medium / 0 tracking
- Caption: 11px / normal / 0.02em tracking

### Border Radius
**Scale:**
- `sm`: 4px (inputs, small badges)
- `md`: 6px (buttons, cards)
- `lg`: 10px (dialogs, large cards)
- `xl`: 14px (modals)

### Borders
**Progression:**
- Subtle: `oklch(1 0 0 / 8%)` (background edges)
- Default: `oklch(1 0 0 / 12%)` (card borders)
- Emphasis: `oklch(1 0 0 / 20%)` (active states)

### Status Semantic Colors
**Light mode:**
- Confirmed: `bg-emerald-50 border-emerald-200 text-emerald-700`
- Pending: `bg-amber-50 border-amber-200 text-amber-700`
- Cancelled: `bg-rose-50 border-rose-200 text-rose-700`
- No-show: `bg-orange-50 border-orange-200 text-orange-700`
- Completed: `bg-sky-50 border-sky-200 text-sky-700`

**Dark mode:**
- Slight desaturation, lower opacity backgrounds

## Patterns

### Card
- Background: `bg-card`
- Border: `border` token
- Radius: `md`
- Padding: `p-4` (compact) / `p-5` (default)

### Status Badge
```tsx
<span className="inline-flex items-center gap-1.5 rounded-full border px-2 py-0.5 text-xs font-medium">
  {icon}
  {label}
</span>
```

### Input
- Background: `bg-input` (darker than surface)
- No heavy borders by default
- Focus ring via `ring-3 ring-ring/50`

### Layout
- Sidebar: Same background as main, subtle border separation
- Content: Max-width 6xl, centered
- Padding: `px-4 sm:px-6`

---

## TODO

- [x] Status tokens in CSS variables
- [x] Refactor status badges to use semantic classes
- [x] StatusBadge component created
- [x] Home panel redesign with metrics + timeline

## Home Page Patterns (v2)

### Structure
- Header + URL Card: 2-column grid (lg:)
- Main: Timeline de reservas
- Sidebar: Stats grid consolidado (sticky)

### URL Card (destacada)
```tsx
<div className="group relative overflow-hidden rounded-2xl border border-blue-200/60 bg-blue-50/50 p-5">
  <div className="absolute inset-0 bg-gradient-to-br from-blue-50/80 to-blue-100/30" />
  <div className="relative flex items-center justify-between gap-4">
    <div className="min-w-0 flex-1">
      <p className="text-[11px] font-semibold uppercase tracking-[0.28em] text-blue-600/70">
        Reserva online
      </p>
      <a href={url} className="mt-1 block truncate text-sm font-medium text-blue-700 underline-offset-2 hover:underline">
        {url}
      </a>
    </div>
    <button className="relative flex shrink-0 items-center gap-2 rounded-lg bg-blue-500/10 px-3 py-2 text-sm font-medium text-blue-700 transition-colors hover:bg-blue-500/20">
      <Copy className="size-4" />
      <span>Copiar</span>
    </button>
  </div>
</div>
```

### Stats Pills (header)
```tsx
<span className="rounded-full border border-emerald-200/60 bg-emerald-50/60 px-3 py-1 text-xs font-medium text-emerald-700">
  {count} hoy
</span>
```

### Stats Sidebar (grid 2x2)
```tsx
<section className="space-y-3 rounded-2xl border border-border/70 bg-card p-4">
  <h2 className="text-xs font-semibold uppercase tracking-[0.28em] text-muted-foreground">
    Resumen
  </h2>
  <div className="grid grid-cols-2 gap-3">
    <div className="rounded-xl border border-border/50 bg-background/80 p-3">
      <p className="text-xs text-muted-foreground">Total</p>
      <p className="mt-1 text-xl font-semibold tracking-tight">{value}</p>
    </div>
    <div className="rounded-xl border border-emerald-200/40 bg-emerald-50/40 p-3">
      <p className="text-xs text-emerald-700/80">Hoy</p>
      <p className="mt-1 text-xl font-semibold tracking-tight text-emerald-700">{value}</p>

### Timeline Item (v2 - mejorado)
```tsx
<div className={[
  'group flex items-center justify-between gap-3 rounded-xl border border-border/70 bg-card/60 p-3.5 transition-all hover:bg-muted/50',
  isPast && 'opacity-50',
  isNow && 'border-l-2 border-l-emerald-500 bg-emerald-50/30',
].join(' ')}>
  <div className="flex min-w-0 flex-1 items-center gap-3">
    <div className="flex w-14 flex-col items-center">
      <span className="text-sm font-medium tabular-nums">{startTime}</span>
      <span className="text-[11px] text-muted-foreground">{endTime}</span>
    </div>
    <div className="min-w-0 flex-1">
      <p className="truncate text-sm font-medium">{courtName}</p>
      <p className="truncate text-xs text-muted-foreground">{customer}</p>
    </div>
  </div>
  <div className="flex shrink-0 items-center gap-2">
    <StatusBadge status={...} />
    <div className="flex gap-1 opacity-0 transition-opacity group-hover:opacity-100">
      <Button size="icon-xs" variant="ghost" title="Marcar cumplida"><Check className="size-3.5" /></Button>
      <Button size="icon-xs" variant="ghost" title="Cancelar">×</Button>
    </div>
  </div>
</div>
```
