/* patchnotes ops — "Aurora" design system (v3, 2026-08-21).
   Inspired by modern SaaS dashboards: dark-first, generous whitespace,
   soft layered surfaces instead of hard borders, large radii, pill
   controls, one restrained accent with a subtle glow. Light theme is a
   fully-designed counterpart. Server-rendered; JS = theme toggle,
   actions poll, models confirm, copy buttons, list filters, live char
   count — nothing else. */
