/* ChaCha grader app stylesheet.
   Light theme with Hovercam-brand orange:
   - --accent (#E85A14): darker orange for primary buttons + links;
     deeper than the logo's #FF641A so it clears AA contrast on white
   - --accent-brand (#FF641A): the exact logo orange, used on brand mark
   - --accent-2 (#FF8A4D): lighter orange for gradient ends + soft hovers
   - Text stays near-black with a faint warm cast.
   App CSS lives separate from site/styles.css so the two surfaces can
   diverge as the product grows; both share this palette. */
