/* ==========================================================================
   /calculator/ai-text-generator/ — AI text cleaner, restored 2026-10-11.
   Same page language as /calculator/banner-creator/ and /calculator/signature/:
   the theme tokens, a 6% accent tint for surfaces, radii 22/16/10, the
   contact-form field recipe, the shared .btn and the portfolio.css orbit.
   Mobile First, every rule scoped under .atg-page.

   Breakpoints: 768px (the two text panes side by side), 1100px (editor and
   settings side by side, settings sticky), 1200px (orbit shown).
