218-218: Verify that the UFH Desmos calculator link matches the 4.2.1 release.

The link formatting is correct and consistent with the Radiators section above. However, please confirm that this Desmos calculator URL (https://www.desmos.com/calculator/i7f7uuyaoz) is the correct/updated version for the 4.2.1 release.

214-215: Desmos calculator link verified for 4.2.1 release.

In `@README.md`:
- Line 214: The heading text "Radiators or Mixed Syestems:" contains a spelling
mistake; update that exact string (look for the heading "Radiators or Mixed
Syestems:") to read "Radiators or Mixed Systems:" so "Syestems" is corrected to
"Systems".
- Around line 214-218: Fix the spelling typo in the heading string "Radiators or
Mixed Syestems:" by changing it to "Radiators or Mixed Systems:" and while here
verify the two Desmos links (https://www.desmos.com/calculator/spfvsid4ds and
https://www.desmos.com/calculator/i7f7uuyaoz) remain unchanged and working;
update only the misspelled heading text (the label used in the README) and do
not alter the URLs or their formatting.
