   Layout: a masthead with the Massachusetts State House standing on the hero's bottom rule,
   then the projects as wide rows, then a short About.
   Boston in the details: Patriots navy and red run the page, project numbers sit on
   Green Monster scoreboard plates, the footer carries a BC maroon and gold stripe,
   and at night the State House windows light up under its gold dome.
   Every color is a variable below, so a palette change happens in one place. */
