fix(seasonal): keep Arcade + Deep Space overlays out of the chat text

Arcade: - perspective grid is masked through the central timeline column so it frames the chat instead of striping messages; lower opacity, thinner non-scaling strokes (also fixes the grid vanishing in the 76px swatch) - neon horizon line is broken through the middle so it never underlines a message; softer sun glow - "1UP" score + "INSERT COIN" moved from top-left/bottom-centre (space bar / composer) to a single bottom-right HUD stack; font-size clamps to 0 via cqw inside the settings swatch so no more clipped glyphs - scanlines: 4px pitch at lower opacity (light theme was fully striped); ambient wash slightly lighter Deep Space: - starfield 28 → 62 stars across the two parallax layers - base violet wash slightly lighter for light themes SeasonalPreview wrapper is now a size container (container-type) so overlays can scale/hide fixed-px details with cqw. LOTUS_FEATURES.md theme table now describes what both overlays actually render.
