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.

Split the 808-line SeasonalEffect monolith into one self-contained module per
theme under seasonal/themes/ (<Theme>.tsx + <Theme>.css.ts), and gave every
theme a premium, research-backed redesign (one Opus agent per theme against a
shared brief). SeasonalEffect now just imports the 11 overlays and dispatches;
the orphaned shared Seasonal.css.ts is removed (each theme owns its keyframes).
Each overlay: layered oklch palettes, GPU-only animation (transform/opacity),
`contain: layout paint style` to kill repaint flicker, ≤~40-element perf budget,
particles seeded once via useMemo (no per-frame state), a gorgeous STATIC
prefers-reduced-motion form (the settings preview thumbnail), WCAG-AA-preserving
low opacities, and no new deps / no external assets (inline SVG data-URIs,
Tauri/CSP-safe).
Themes: Halloween, Christmas, New Year, Autumn, April Fools, Lunar New Year,
Valentines, St. Patrick's, Earth Day, Deep Space, Arcade.
Gates: tsc clean, ESLint clean, Prettier clean, build OK, 551 tests pass.
