Regler

# Regler

## Philosophy

A restrained, functional-minimalist interface language in the Dieter Rams / Braun tradition: a warm bone ground, graphite controls, hairline keyline separation, knurled-dial hardware, and tabular readouts. The signature mechanic is the regulator track — every control reads as engineered instrumentation, and exactly one burnt-orange line marks what is live. Importance is registered to a slot, never flooded with colour.

### Values

- usefulness before novelty
- clarity through reduction and keyline separation
- controls that communicate their function and state
- honest hierarchy from spacing and alignment, not loud display

### Anti-Values

- decorative flourish without an idea
- gloss, glass, gradients, or pastel washes
- accent colour used as a background fill
- ambiguous controls or unstyled browser defaults

### Shadows

- **Sm**: 0 1px 0 rgba(23,25,26,.06)
- **Md**: 0 10px 24px rgba(23,25,26,.07)
- **Lg**: 0 22px 44px rgba(23,25,26,.10)
- **Inset**: inset 0 0 0 1px #CFC7B8

- **Easing**: cubic-bezier(0.2,0,0.2,1)
- **Philosophy**: deliberate

## Rules

### Composition

Compose every screen as a calm instrument panel: a summary zone of meter-plates, clearly segmented modules each opening with a mono overline and a hairline rule, and controls that sit in defined slots on a shared baseline.

### Hierarchy

Hierarchy comes from spacing, alignment, keyline separators, and label/value pairing — not oversized display. Scale is used sparingly.

### Density

Medium density with disciplined breathing room; panels hold many controls, but every control has a defined slot and measured padding.

### Signature

The regulator track: knurled rotary dials with one burnt-orange pointer, inset level-meters, segmented pills, physical switches, and tabular mono readouts — selected/live states marked only by a restrained burnt-orange line, dot, or fill, never by flooding the panel.

## Layout

### Grid

A 12-column desktop grid collapses to 8 on tablet and a single measured column on mobile; modules span whole columns rather than arbitrary card widths.

### Whitespace

Deliberate and even — consistent gutters and module padding over dramatic voids; every gap should feel engineered.

### Density

medium

### Responsive

Renders from ~390px to 2560px+; minmax(0,1fr) columns and min-width:0 children keep grids contained; only the full-bleed hero spans 100vw, contained content capped and centred on ultra-wide.

### Breakpoints

- **Mobile**: 375
- **Tablet**: 768
- **Desktop**: 1440

## Guidance

### Do

- Separate content with keylines, surface, and measured space before reaching for colour.
- Make every control self-explanatory with a label, a value, and a visible mechanical state.
- Reserve burnt-orange for the one thing that is live, active, focused, or filling a meter.

### Don't

- Do not flood a surface with accent colour or add a second bright hue.
- Do not add gloss, glass, gradients, or decorative blobs.
- Do not lean on an oversized hero headline when alignment and labelling do the work, or box the nav into a floating pill bar.
- Do not leave any form control as a browser default.

### Accessibility

High contrast graphite ink on warm bone; body 17px+; burnt-orange focus rings on every control; status conveyed by labelled pills and dots, not colour alone; respects prefers-reduced-motion.

## Imagery Direction

### Pairs With

werkbild

### Summary

Subjects rendered in the Werkbild product-plate technique — one precisely engineered Braun-style object, matte powder-coated panels, a knurled monochrome control, raking upper-left light, a faint keyline grid behind, and exactly one burnt-orange signal element on a warm bone-and-graphite monochrome field.

### Subjects

- control regulators and dials
- instrument panels and consoles
- powder-coated product casings
- engineered modules and recessed slots

### Usage

One full-bleed hero per landing (--hero-image); feature imagery sits behind a graphite overlay panel for legibility. Never use illustrated/generated art for the thumbnail.

## shadcn/ui Usage

When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.

DESIGN.md with shadcn: `/language/en-019ef8e6-6b2f-72b1-8d00-bfeedc4d9806/DESIGN.with-shadcn.md`.

The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.

Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.
