/* SOVRA — "Messagerie de confiance". Deliberately single light theme.
   Layout: airy white pages with pastel bands; rounded cards with soft shadows; app screenshots and friendly illustrations carry the story.
   Brand: modernised Moroccan flag colours, emerald green (brand, action, security) and carmine red (accent, sovereignty, used sparingly); slate blue for cryptographic data. Rounded, readable type. */
