Override --font--colors--title-dm/paragraph-dm variables that resolved
to near-black after neutral color inversion. Add comprehensive dark
mode overrides for header nav links (#222 hardcoded), footer text/links/
borders, cards, CTA sections, contact page elements, and more.
Remove inline color styles from contact components that blocked CSS
dark mode overrides. Fix truncated about section text and add w-mod-ix3
class to html element.
