/* ===== readability tweaks for PDF highlights =====
These overrides are intentionally minimal and low-risk:
- lower the fill opacity so highlights don't wash out text
- disable any backdrop-filter on highlight elements
- avoid highlights capturing pointer events (so selection/cursor stays reactive)
- use mix-blend-mode to reduce visual "softening" on top of rendered text
Tweak the rgba alpha values below to taste (0.08 - 0.18 work well).
