/* ============================================================
   Post illustrations — black-on-transparent line-art PNGs.

   Markdown classes (set via attr_list, e.g. `{ .illu-thumb }`):
     .illu-thumb   default — float right, wraps text on left
     .illu-left    modifier — flip to float left

   Sizing is contextual:
     - Inside .md-post--excerpt (blog index card) → small thumbnail
     - On the post page itself                  → hero (max 512px)

   Dark-mode recolor: PNGs ship pure black, so a single CSS filter
   inverts black → light gray. No mask wiring needed, no per-image
   --src plumbing — works directly on the markdown-emitted <img>.
