SUMMARY

Implements necessary changes for #15

Reviewers: @numere-org/maintainers

IMPLEMENTATION

• Implementation: Disabled an not necessary double-render due to an added new line character and buffered the current managed line during rendering to avoid the costly reconstruction on every virtual line break.
• Implementation test: Executed url "https://www.numere.org/home" and the rendering took only a few milliseconds instead of 4 seconds
