Coffee Ratio Calculator

A focused SvelteKit app for dialing in pour-over coffee. Enter either beans or water, pick roast level and cup quality, and get a tailored ratio plus temperature/grind guidance. The app remembers your last settings in local storage so you can keep tweaking between brews.

Features

• Two modes: calculate water from beans or beans from water.
• Roast-aware ratios: light, medium, and dark recommendations.
• Quality toggle: high-clarity vs. lower-ratio, fuller body.
• Brew guidance: suggested temperature and grind size per recipe.
• Kitchen-friendly hints: approximate heaping tablespoon conversions.

Tech Stack

• SvelteKit + Svelte 5
• Tailwind CSS (with typography + forms plugins)
