     READING SURFACES

     These were missing. Every rule that wanted a slightly raised panel
     inside a card wrote `var(--soft, #f7f9fc)` — and because --soft was
     never defined anywhere, the fallback won every time. #f7f9fc is almost
     white, and the body text on it is --ink, which is also almost white.
     So Key terms, Worked example, In the exam and the whole literature
     shelf rendered as white on white: there, selectable, and invisible.

     Defining them here fixes every one of those rules at once. Anything
     that needs a raised panel uses --soft; nothing hard-codes a colour.
