/* Bumelerze website — single shared stylesheet.
 * Tokens follow the app's design language (.claude/research/design-language.md):
 * dark as the primary theme, true-black OLED surfaces, Zagros Blue brand hue
 * pulled from src/theme/palette.ts (light #1F4E5F / dark #3E7C93), big type,
 * system font stack, no images, no frameworks. RTL locales (ckb, ar) rely on
 * dir="rtl" + the CSS logical properties used throughout — nothing here is
 * hard-coded left/right.
