Subject: feat(theme-selector): two-column layout, contrast ratings, taller
 samples

I restructured the page into ordered rows. The top row splits palette on the left and save / load theme on the right. The next row, "code/color assignments," puts the assignment table on the left and a single code sample on the right, picked by a language dropdown and recolored live from the assignments. The last row is the interface faces.

I added a contrast column to the assignment table: each color's WCAG ratio on the current background plus an AAA / AA / FAIL rating, recomputed live and re-rated when the background changes.

I also replaced the six-language scroll with the one-language picker, lengthened every sample to roughly the height of the assignment table, and renamed the title suffix to "theme."
