/* ======================================================================
   /try — PROFESSIONAL DESIGN PASS (v5 "pro" layer)
   ----------------------------------------------------------------------
   Loads AFTER try.css. Pure visual enhancement layer — does not touch any
   JS hook (ids / structural classes). Elevates the page from "functional
   dashboard" to a premium SaaS product: layered surfaces, ambient
   backdrop, glass panels, sharper type hierarchy, tinted category pills,
   richer depth, and smoother micro-interactions.

   Strategy:
     - Re-declare design tokens (richer palette, real elevation ramp).
     - Reuse every existing selector; only override paint, not structure.
     - Dark-first; light mode kept tasteful via the same token swaps.
