Firefox served a cached copy of the brewing page after the advice
became a button and a pop-out, so the phone kept showing the old
inline advice - a long paragraph in the table cell, with the button
label reading "Read the adviceAdvice".
Two separate causes:
The pages had no cache headers, so Firefox was free to reuse them.
They now send Cache-Control: no-store, must-revalidate.
The rule that hides the short label was scoped to `table.data .short`,
so it did not apply to the advice button's label. A stale stylesheet
then showed both forms at once. The rule is now on `.short` alone, so
it applies wherever the pattern is used - a table heading, the advice
button, the Active Beers page - and only ever one form can show.
Verified at 390px and 1280px: the phone shows "Advice", the desktop
shows "Read the advice" and "BREWING ADVICE", and no element ever
shows both.
192 tests pass.
