/* Performance site home page.

   Shares the palette and the status colours with the punctuality report so
   moving between them doesn't feel like two products. Same rule applies here:
   status colour never carries meaning alone, because the warning yellow sits
   below 3:1 on the light surface -- every status is also spelt out. */
