/* BASELINE pending Andrew's look&feel session (Direction A "Clean Nimiq-Native", SPEC §9).
 * Palette + type are CSS vars so Andrew's #22 pick swaps in ONE place.
 *
 * The brand palette is now SOURCED from @nimiq/style's canonical --nimiq-* tokens
 * (loaded in index.html BEFORE this file) so the hexes can never drift from upstream.
 * Each var keeps a literal fallback so the app still renders if the CDN is unreachable.
 *
 * nimiq-ui gotcha: @nimiq/style sets html{font-size:8px} (1rem = 8px). All custom
 * values in this file are in px, so the 8px root does not affect them; nq-* component
 * classes assume the 8px root.
