Five Shopify features. No apps.
Paste once. You own the files. €19, not $8–15 a month.
What happens after €19
You get the five files today. The next three (announcement bar, GDPR banner, sticky add to cart) go into the same download for everyone who buys at €19.
KERN does not launch a monthly app. If a file breaks after a theme update, you re-paste. That is the product.
