Do I need all three products? No. Modularis works with a compatible theme without Thematis. Use Derivis only when you need to create a derived theme. Will installation change my active theme or existing pages? No. A Launch Pack installs its declared page tree into an unused target. Your active theme, site identity and existing Pages remain unchanged. Where do I edit text and section order? Edit text and media in native Grav Pages. Manage section composition and order in Page Composer. The active theme controls the global appearance, including the header, navigation and presentation of the whole site. Design Kit provides explicitly enabled component-level adjustments; it does not replace the theme. How do Czech and English content work? Pages use native Grav language files. Translated text remains independent; Composer keeps a shared structure across existing supported parent variants. ## BUILD THE WEB YOUR WAY.
