/**
 * css/rcs-login.css — Sign-in page.
 *
 * Redesigned 2026-09-10, direct feedback: "that login screen is still teal
 * as hell... let's changed up everything about it... give me a nice clean
 * log in with darker colors as the default." Dark is not a toggle here —
 * this page is unauthenticated, so there is no per-user preference to read
 * yet; it is simply designed dark, permanently, using the same navy/teal/
 * warm-copper palette as the marketing site (css/public-home.css) for one
 * consistent brand across every public-facing surface. Teal is kept as a
 * small accent (the monogram, focus rings, links) rather than the page's
 * dominant color — the primary action uses the warm copper accent instead,
 * which is the single biggest change in how "teal" the page reads.
