Blame for app/assets/design_system.css

/* ============================================================
   Upwork Proposal Strategist — "Aurora Glass" design system
   Dark luxury glassmorphism. Luxury through restraint.

   INJECTABLE INTO STREAMLIT via app/ui/theme.py:
     st.markdown(f"[style]{...design_system.css...}[/style]",
                 unsafe_allow_html=True)

   REQUIRED FONT — theme.py injects:
   <link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600&display=swap" rel="stylesheet">

   THEME: tokens live under [data-theme="dark"] / [data-theme="light"].
   theme.py::apply_step_accent sets data-theme on <html> and writes
   --accent-h / --accent-c / --accent2-h inline, so the accent stays a
   single violet family with only a whisper of per-step drift.

   Every custom-property name and every class name in this file is part
   of the contract with app/ui/theme.py and the screen modules. Values
   changed for Aurora; names deliberately unchanged.

/* ============================================================
   DEPTH — Aurora in the round
   ------------------------------------------------------------
   These rules only lift a surface's contents onto their own
   planes. They do nothing on their own: without a `perspective`
   on an ancestor a translateZ collapses to flat, which is
   exactly the safe default.

   The perspective is NOT set here. app/ui/motion_runtime.py sets
   it on a floated surface's parent at runtime, and only when that
   parent passes canMove() — because `perspective` and
   `transform-style: preserve-3d` each make an element the
   containing block for its position:fixed descendants, the same
   hazard as a transform. Putting either on .block-container would
   break the file uploader's drop overlay app-wide.
