   TESOL Flex – visual theme v2 (11/11/2026)
   Based on the TESOL Flex campaign visual: warm ivory paper, soft blue
   rings & light rays, bold navy/red headlines, framed cards with an
   offset colour edge (like the trainer photo frames).
   Loaded AFTER styles.css – remove this file to go back to the old look.
