fix(lotus): transparent-theme contrast guard; phone-only rail shrink; live URL params

Browse Source 
- lotusTransparent without lotusTheme warns and applies the theme anyway;
  name tags/header/footer get a subtle text-shadow + backdrop blur under
  body.lotus-transparent (#21).
- Landscape filmstrip shrink requires (pointer: coarse) so a short
  desktop/PiP window isn't reflowed as a phone (#32).
- lotusParam re-reads window.location on every call (#33).

Fixes #21
