The design language of this project strictly adheres to an **industrial, highly structured, and utilitarian** approach. We completely reject arbitrary styling, intermediate corner radii (e.g., 4px - 12px), and unnecessary ornamentation. Every visual decision must serve a logical structural purpose.

## 1. The Base Grid (0px Strict) [#1-the-base-grid-0px-strict]

All structural UI components and layouts **MUST** use absolute sharp edges (`rounded-none`). This forms the base grid and the structural foundation of the UI. Intermediate soft corners are strictly banned.

<div className="grid grid-cols-2 gap-4 mt-6">
  <div className="border border-border-strong bg-background p-8 flex flex-col items-center justify-center gap-4">
    <div className="text-xs text-muted-foreground font-mono">
      DO (0px Radius)
    </div>

    <div className="border border-border-strong bg-primary text-primary-foreground px-8 py-4 font-medium shadow-xs">
      Sharp Edge
    </div>
  </div>

  <div className="border border-border-strong bg-background p-8 flex flex-col items-center justify-center gap-4 relative overflow-hidden">
    <div className="absolute inset-0 bg-semantic-danger/5 pointer-events-none" />

    <div className="text-xs text-semantic-danger font-mono">
      DON'T (Intermediate Radius)
    </div>

    <div className="border border-border-strong bg-muted rounded-md px-8 py-4 font-medium line-through opacity-70">
      Soft Corner
    </div>
  </div>
</div>

## 2. Floating Meta-Actions (9999px Contrast) [#2-floating-meta-actions-9999px-contrast]

When an action button is "floating" or overlaid on top of a massive structural container (such as a code block or canvas), it must be visually decoupled. Floating utility actions **MUST** use `9999px` (`rounded-full`).

This creates extreme **Geometric Contrast**. The structural container is 100% sharp, while the transient action is 100% curved, instantly signaling a "meta-layer" that sits above the content.

<div className="flex gap-4 mt-6 border border-border-strong p-8 bg-muted relative">
  <div className="w-full h-32 border border-border-strong bg-background flex items-center justify-center relative">
    <span className="text-muted-foreground font-mono">
      Structural Container
    </span>

    <button className="absolute -top-4 -right-4 rounded-full border border-border-strong bg-background text-foreground px-4 py-1.5 text-xs font-medium shadow-sm hover:bg-muted transition-colors duration-[150ms]">
      Floating Action
    </button>
  </div>
</div>

## 3. Monochromatic Idle State [#3-monochromatic-idle-state]

The UI is purely monochromatic in its default state (grayscale/black/white). Accent colors are allowed to appear **only** during transient interactions (hover, active, focus). Exceptions apply for destructive (Danger) and irreversible (Success) actions.

<div className="flex flex-col gap-4 mt-6 border border-border-strong p-6 bg-background">
  <div className="flex gap-4">
    <div className="h-16 w-full bg-background border border-border-strong flex flex-col items-center justify-center text-sm font-mono shadow-xs hover:border-primary hover:text-primary transition-colors duration-[150ms] cursor-pointer">
      <span>
        Hover Me
      </span>
    </div>

    <div className="h-16 w-full bg-semantic-danger text-semantic-danger-fg border border-border-strong flex flex-col items-center justify-center text-sm font-mono shadow-xs">
      <span>
        Destructive
      </span>
    </div>
  </div>
</div>

## 4. Motion: Snappy & Utilitarian [#4-motion-snappy--utilitarian]

All single-direction animations and transitions MUST be snappy and utilitarian. No single movement may exceed **150ms**.
Hover and active states must **never** use `scale` transformations (`scale-*`). Subtle translational animations (`translate-x-1`) are permitted for semantic icons strictly on hover.

<div className="flex gap-4 mt-6">
  <div className="flex-1 border border-border-strong p-8 flex flex-col items-center justify-center gap-4 bg-background">
    <div className="text-xs text-muted-foreground font-mono">
      Hover / Focus
    </div>

    <div className="px-6 py-2 border border-border-strong bg-muted hover:bg-primary hover:text-primary-foreground transition-all duration-[150ms] ease-out cursor-pointer text-sm font-medium group flex items-center gap-2">
      <span>
        Snappy Color Transition
      </span>

      <span className="group-hover:translate-x-1 transition-transform duration-[150ms]">
        ->
      </span>
    </div>
  </div>
</div>

## 5. Focus Rings & Structure [#5-focus-rings--structure]

To maintain maximum sharpness, focus outlines MUST default to `1px` thickness (`ring-1`). Thick outlines contradict the minimalist aesthetic.

<div className="flex gap-4 mt-6">
  <div className="flex-1 border border-border-strong p-8 flex flex-col items-center justify-center gap-4 bg-background">
    <div className="text-xs text-muted-foreground font-mono">
      DO (ring-1)
    </div>

    <input type="text" placeholder="Focus me" className="px-4 py-2 bg-transparent border border-border-strong outline-none focus-visible:ring-1 focus-visible:ring-primary focus-visible:border-primary transition-all duration-[150ms] text-sm" />
  </div>
</div>
