/* The look: a pale blue-grey page, a slim bar on top, a strip of folder tabs, one white card in a pale-blue frame,
   slate headings, navy links and pale-lime module headers. System fonts only.
   One deliberate change: the button's light end is darker than the original #5a9a34, where white text is only 3.44:1. */
