/* Play Flags — shared stylesheet
   Matches the original site's visual grammar as closely as possible:
   - ONE blue outer frame (#0000FF) around the whole page, sharp corners.
   - Yellow (#FFFF00) used ONLY as thin, full-width horizontal divider
     lines between major sections — never as an underline/accent/box border.
   - No grey panel boxes. White page, white frame interior.
   - No rounded corners anywhere. */
