Walkthrough

The update refines the logic for extracting article content using the Readability library. It introduces stricter checks to ensure the article and its text content exist before processing, and changes a variable declaration from let to const. The function now continues with additional logic if the article extraction fails.

Changes

File	Change Summary
src/utils/get-core-content-text.mjs	Improved article extraction logic: stricter null checks, let to const, altered control flow.

Poem

In codey fields where rabbits hop,
We check for nulls and never stop.
With const in paw, we leap ahead,
Ensuring text is rightly read.
If articles hide or run away,
Our logic finds another way!
