 summary: A line-based, interpreted scripting language and terminal code editor
 description: |
   YesNt is a line-based, interpreted scripting language. The core idea is simple: each line maps to one primary statement. Lines are processed top-to-bottom, and inline tokens (like `${variable}` or `%read_line`) are substituted before the statement executes. Postfix modifiers like `calc` and `task` can also appear at the end of a line to evaluate arithmetic or fork execution into a background thread.
