   "Objects at the Command Line" — Rouge syntax theme
   Makes Jekyll's Smalltalk code blocks match the series cards.

   USAGE (Jekyll):
     1. Ensure _config.yml has:   markdown: kramdown
                                  highlighter: rouge
     2. Drop this file into assets/css/ and @import or link it.
     3. Write fenced blocks as:   ```smalltalk
     4. Do NOT also load a rouge theme via `rougify style` — this replaces it.

   Token classes below are the ones Rouge ACTUALLY emits for GNU Smalltalk
   (verified by lexing our real after.st, not guessed).
