Method: reviews are classified into a fixed complaint taxonomy by an automated reader; every category shown is backed by at least two verbatim quotes from distinct reviews. Trends are computed from dated review counts only. Negative reviews are deliberately over-sampled for evidence depth; headline percentages use an unbiased recent sample only.
