/*
 * Paleta clara da Unexly ("Sinal claro"). Fonte única de verdade para a página
 * inicial e para /como-funciona: as duas usam este bloco :root sem mudar os
 * valores. Pode acrescentar tokens novos, nunca alterar estes.
 *
 * Linguagem: prancha técnica sobre papel. O que no escuro era brilho vira traço
 * preciso, hachura e preenchimento chapado. Nada de glow, sombra difusa ou
 * degradê genérico.
 *
 * Contraste medido (WCAG) sobre --bg #f4f1e9 / --panel #fbfaf6:
 *   --text #15243a 13.8 / 15.0   --text-2 #39445a 8.7 / 9.4   --muted #5d6a7f 4.9 / 5.3
 *   --info #06737a 5.0 / 5.4     --state #b4441c 4.9 / 5.3    --accent #5a3fd1 6.1 / 6.6
 *   Preenchimentos (--cyan, --coral, --violet) NÃO servem para texto pequeno sobre
 *   o papel (1.8 a 3.0). Texto sobre --cyan usa --text (7.6); sobre --coral usa
 *   --text (5.0); branco sobre --info dá 5.6.
