/* Balanced text mode (opt-in via body class). Two complementary moves:
   (1) every long paragraph (hero tagline, section intros, callout body
   copy) gets a justified right edge — no more ragged-right on wide
   screens; (2) sections that pair an intro paragraph with a multi-column
   layout below (info-cards, skill-matrix, results-grid, skills-grid)
   shrink their container to 1040 px and pull the intro flush-left, so
   the intro and the cards share the same horizontal column instead of a
   narrow centred intro hovering above wide cards. Hero, code-tree, prose
   sections without multi-column layout keep the original 1180 px
   container — only their text justification changes. */
