/* Promptra — promptra-ai.netlify.app

   Palette derives from the app's own PromptraTheme, warmed up for the web.
   The app can afford stark near-black because it's a full-screen tool you
   point at your face; a website read at arm's length needs more warmth or it
   reads clinical. So the base carries a plum tint rather than being neutral,
   text is a warm off-white rather than pure #fff, and the icon's pink appears
   as a second accent to stop everything being cold cyan.

   No JavaScript anywhere on this site. Motion is CSS-only, the FAQ is native
   <details>, and the CSP can stay at script-src 'none'. */
