/* ai-standalone.css — form controls for the custom /ai/* frontends.

   The page shell (header, hero, card lift, about, more-tools, footer and the
   --tt-* tokens) is shared with /tools/* via tools-standalone.css, which loads
   first. This file only adds the widgets the AI pages need, styled to match the
   tool pages exactly: flat, sharp-cornered, #ee5057 primary on white/#fafafa.

   The widget half (.ai-input/.ai-select/.ai-textarea/.ai-btn/.ai-bar/.ai-drop/
   .ai-file/.ai-hint) is generic, so /tools/custom/ and /tools/publish/ load this
   sheet too rather than growing a second copy of the same controls. */
