/* Word Frequency & Keyword Density Counter — content styles.
   Prefix: --wf-  /  .wf-

   Reference point: a ranked, numbered table of top words IS the result —
   not a single hero metric. The 3-metric row (total/unique/ratio) is
   secondary context above it. Distinguishes itself from this cluster's
   other text-input tool (flesch-kincaid-readability-analyzer, which uses
   a serif textarea and violet neutrals with a single hero score) by
   using a plain sans textarea, warm-neutral palette, and a ranked list
   as the centerpiece instead of a hero figure.
