/*
 * Noura landing page: one sheet for both languages.
 *
 * Direction is never assumed: spacing and alignment use logical properties (inline-start/end), so
 * the Persian page (dir="rtl") and the English one (dir="ltr") share every rule. The few things CSS
 * has no logical form for (gradients, transform-origin) are paired under [dir] at the point of use.
 *
 * Every colour is a token below, and every token is the app's own (Caloriyab/app/globals.css), light
 * and dark. Macro colours are fixed roles exactly as in the app: protein pomegranate, carbs saffron,
 * fat firoozeh. Graphics take --protein / --carb / --fat; text on the page takes the -ink forms.
 *
 * Type floor: nothing under 12.75px (0.797rem), the app's own floor.
