Build a single-page calculator that helps home cooks figure out exactly how much salt to add to their pasta water.

The user enters two inputs: the **amount of water** (in liters or quarts, togglable) and their **preferred saltiness level** (a 3-step selector: lightly salted, properly salted, or "restaurant style" salty). The app instantly displays the recommended grams and teaspoons of salt to add.

Below the result, show a small visual cue — a simple color-coded water droplet or pot icon that shifts from pale blue → medium blue → deep blue based on the saltiness level chosen.

The page should also display a fun one-liner tip about why salting pasta water matters (pick from 4–5 hardcoded tips that rotate each time the inputs change).

No backend, no auth, no persistence required — just a clean, usable single-page widget a home cook could actually pull up on their phone while standing at the stove.
