/* OpenSchool — wit met het geel van bcode. Eén bestand, ingebed in de binary.
 *
 * Identiteit: helder wit, bcode-geel (#fee162) als accentvlak, bijna-zwarte
 * inkt voor tekst. Geel is licht, dus het draagt nooit witte tekst — het is
 * een vlak/markering, met donkere inkt erop. Bewust licht gehouden (zoals een
 * schoolplatform hoort te ogen): geen dark mode, wél overal expliciete kleuren.
