/*
 * Art direction "Interface en jeu": colours and fonts taken from the Civ VI
 * base-game UI files (Base/Assets/UI):
 * - Civ6_Styles.xml, most used colours: #070F17, #051D33, #102B43 (16,43,67),
 *   #294A6C (41,74,108), text #D0D4D9 (208,212,217);
 * - Civ6_ColorAtlas.xml: GoldMetal #CBAD73, GoldMetalDark #826F4B,
 *   Science #44B3EA, Civ6DarkRed #981E1E, COLOR_MEDIUM_GREEN #076E27,
 *   Emergency_Bronze #CE7C33.
 * Not from the game: --muted, --panel-hi, and --partial (Emergency_Bronze
 * darkened so that white text stays readable), chosen here.
 * Colour-blind mode (html.colorblind, js/core/settings.js): --ok becomes
 * Okabe-Ito blue #0072B2 and --ko a neutral grey #4A5058 (chosen here);
 * --partial is unchanged.
 * Fonts: the game uses Minion Pro (titles) and Myriad Pro (text), Adobe
 * commercial fonts; the site uses the free Crimson Pro and Source Sans 3
 * (Google Fonts, index.html) as look-alikes, not equivalents.
