/* Namaste Nepali — motyw aplikacji.
 *
 * Noto Sans Devanagari (import wyżej — `@import` MUSI stać przed każdą regułą)
 * składa nepalskie pismo. Znak marki to pliki w `public/brand/` (źródła
 * i skrypt budujący: `design/logo/`), patrz `.bm-logo` niżej.
 *
 * Serwowany przez platformę jako `/theme.css` (poza pipeline'em Tailwinda —
 * `@theme inline` z tokenami shadcn dokłada CLI). Tu żyją WYŁĄCZNIE wartości
 * zmiennych + kilka klas pomocniczych; klasy `bg-primary`, `text-foreground`
 * itd. działają, bo poniższe `:root`/`.dark` wypełniają tokeny platformy.
 *
 * Kolor przewodni to granat z flagi Nepalu i logo (#003893 = oklch(0.375
 * 0.159 261)); tła i neutralne powierzchnie mają lekki odcień tego granatu
 * (hue 261). Zieleń zostaje tylko tam, gdzie coś znaczy: "dobrze" i kolor
 * lekcji `green`.
