Text Cleanup & Consolidation

I have a collection of separate plain-text snippets that need to become one clean, continuous .txt file. The job is straightforward: lift every text element exactly as it appears, strip out any stray line breaks, duplicates, or obvious typos, and then stitch everything together into a single plain-text document. No images or formatting tricks are involved—this is purely about tidying text.

What I will hand over: multiple plain-text sources.
What I need back: one well-ordered, error-free .txt file containing every element in the original order (unless you spot a clear sequencing issue and flag it).

Before delivering, please run a quick spell-check and remove any empty lines so the final file reads smoothly from top to bottom. Once complete, send me the consolidated file for a final skim, and we can wrap up.
