## Where to use it

The short delay is what makes this tooltip pleasant in busy interfaces. It suits keyboard shortcut hints in a web app (“Shortcut: ⌘ + S” under a Save button), the toolbar of a design tool or the formatting buttons of a text editor. Nothing flashes when the mouse just passes by; linger and the label sharpens out of a blur.

It is aimed at people who already know the tool and want a reminder. Beginners may not wait long enough to see it, so don't hide essential instructions there. It hides faster than it appears, which keeps the interface feeling responsive.

## Code

### HTML

```html
<button class="uv-tb">Save<span>Shortcut: ⌘ + S</span></button>
```

### CSS

```css
.uv-tb {

  /* tamaño */
  --k: 1;
  /* velocidad */
  --fg: #1d1d1f;
  /* texto */
  --bg: #f5f5f7;
  /* fondo */

I want to add the “Delayed blur tooltip” block (Tooltips) from AIMRAN Library to my project.

## What it is
A tooltip that waits half a second before fading in from a blur, and disappears quickly when you leave.

## Chosen settings
- Main color: #0071e3
- Secondary color: #8ec5ff
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Shortcut: ⌘ + S"

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
