/* FilmEU Partner Holiday Calendar
   Palette from the FilmEU brand sheet:
     #00A9CC cyan   - public holidays, primary actions
     #ED1B2F red    - school closures
     #D3E0E2 pale   - surfaces and rules
     #606161 grey   - secondary text
     #000000 black  - text
   Countries are deliberately NOT colour-coded: eight arbitrary colours would
   fight the brand and stop being distinguishable. Country codes are labelled
   instead, and colour carries the one distinction that matters. */
