Whitespace-only polish of solution.tex: 46 chktex warnings fixed
- W2 (43x): 'word \eqref{...}' -> 'word~\eqref{...}' and continuation-line
joins so references stay glued to their prose
- W24 (3x): \label glued to the \begin{...} line
- W8 kept (5x, all in the DOI identifier 10.1090/S0025-5718-1965-0194620-7:
single hyphens are correct there, not prose dashes)
Verified: chktex W2+W24 = 0 (total 128, all W3/W25 brace suggestions + W8
DOI false positives); pdflatex 3-pass clean build (0 errors, 0 warnings,
0 overfull, 17 pages, 0 '??'); token-level PDF text diff vs the shipped
e85d7bf9 PDF shows only glyph-extraction/wrap artifacts (content identical,
whitespace-only tex diff).
NOTE: this is the parallel audited line (492c8ab provenance), NOT the
authority manuscript (completed-submissions 1cbb5982, hand-maintained,
must not be regenerated).
