/* =========================================================================
   REPUTIFLY PROFESSIONAL -- the exact design system of Reputifly Mail.
   White, polished, Inter everywhere. Apple-grade LIGHT UI for client-facing
   software. Primary #007aff with EXPLICIT white text. Full pill rounding.
   Soft neutral shadows. cubic-bezier(0.25,0.8,0.25,1) easing. >=44px tap targets.

   Framework-agnostic: plain CSS custom properties + component classes. Paste
   verbatim into any project (HTML/CSS, React, Vue, Svelte, etc.). Pair with the
   Inter webfont (see the <link> in SKILL.md). For a Tailwind v4 project, change
   the ":root {" line below to "@theme {" and keep everything else.
