   Fluid Block Spec v3 — shared foundation
   Text-style classes (§3.3), responsive scaling (§3.4), shared button
   component, and Section Base wrapper used by every `bs-*` section.
   Prefixed `ts-` / `bs-` so nothing collides with existing theme classes
   (design-system.css already ships `.text-h1…h4` / `.text-body`).
