/*
 * Self-hosted stylesheet for the Lead Upload webapp.
 *
 * This replaces the Tailwind CDN script (cdn.tailwindcss.com — explicitly
 * not supported for production use) and the Google Fonts Inter import.
 * Since there's no Node/npm toolchain in this environment to run the real
 * Tailwind compiler, this file hand-implements exactly the utility classes
 * used across templates/*.html (verified by grepping every class="..."
 * attribute and every JS classList.add/remove call) with the same values
 * Tailwind's defaults use, plus this project's custom "brand" color scale
 * from the old inline tailwind.config block. Font: a system-font stack
 * instead of a fetched Inter webfont, so the page never needs any network
 * request to render — it looks near-identical and has zero external deps.
 *
 * If the class surface grows, add the new utility here rather than
 * reintroducing the CDN script.
