/*
  YANTRA — Sadhna / Breathwork Engine
  Full rebuild (2026-08-07): the old vertical single-column practice page
  (Quick Start grid → horizontal pattern strip → practice panel → journal →
  science accordion) is replaced with a three-column instrument layout —
  pattern library (left) · breathing stage (center, dominant) · pattern
  detail + controls (right) — same spirit as the master Breathwork Engine
  prompt Ashish supplied. Every color below still traces back to the same
  eight --sad-* tokens this page has always used (light = paper/ink/forest/
  gold/vermillion, dark = deep navy + antique gold) — no new palette, no
  glassmorphism, no photographic backgrounds. The reference mockup's
  top-bar/"Device Connected" chrome is intentionally NOT reproduced — this
  page lives inside YANTRA's real shell (yantra-topbar/yantra-sidebar),
  exactly like every other pillar page, so it reads as part of the app,
  not a bolted-on product.
