   Tamerix -- Issue 01: Transformer
   Page-specific styles for issues/transformer/index.html.

   Loaded after assets/core.css. This file owns:
     - prose marks (why-card, math-card, takeaway, callout, note)
     - form chrome used by the translation input
     - math visualization primitives (token-pill, num-grid, heatmap,
       bars, iter-card, architecture diagram)

   New issue authors: copy this file as a template. Anything below
   that you don't use, delete. Anything missing, add at the bottom.
