       The user said "darker font" as a complaint. They want it brighter?
       Let's try var(--text-secondary) but maybe bump opacity or use a brighter color?
       Actually, let's look at :root. 
       --text-primary: #f8fafc (white-ish)
       --text-secondary: #94a3b8 (grey-ish)
       If they say "use darker font" they might mean "it currently uses darker font and I don't want that".
       "the subchapters ... use darker font" -> implies this is bad.
       So I should use --text-primary or something closer to it.
       Let's use a custom color or just --text-primary with slight opacity to distinguish?
       Or just --text-secondary but maybe it's too dark on their screen.
       Let's try setting it to --text-primary but maybe 0.9 opacity? 
       Or just stick to --text-primary for high visibility given the complaint.
