/*
 * THE PUBLIC PAGES' ONE STYLESHEET -- index, volunteer, request_access, enroll, privacy, terms.
 *
 * Owner, 2026-10-21: "I would like to see our public facing URLs to also be updated with better contrast for
 * more readability. This isnt a constant monitoring UI like Central Control, so providing better contrast
 * using lighter colors is needed. Also, make the public facing websites be more elegant, but still simple. We
 * should have some graphics that are relevant to our EVA brand as well."
 *
 * Light ground, dark ink, the brand's blue and signal red-orange as the only accents (from the EVA mark:
 * blue route lines, red-orange warning triangle). Body text #1c2838 on white is 14.9:1; muted text
 * #47566a is 7.5:1; the blue #0a66d6 used for links and primary buttons is 5.4:1 on white, and
 * white on it the same -- every pairing above WCAG AA, most above AAA.
 *
 * NO THIRD-PARTY REQUESTS: no web fonts, no CDN. /enroll carries a credential in its address, and a page that
 * asks people for their details is better for not calling anyone else. The system font stack is used instead.
