PICK SEA slot interaction: cover/cross appear animation; focused glow; card bg fully opaque

- cover/cross card slots animate 0→1→resting opacity (2s) on deposit
- cover rests at 0.3; cross rests at 0.15; hover reveals to 1
- first-tap focus adds diffuse --ninUser + tight black box-shadow glow
- second tap removes --focused before _showStage() — glow dismisses as modal opens
- levity/gravity card backgrounds bumped to rgba alpha 1 (were 0.85)
- box-shadow 0.15s ease added to --visible transition for smooth glow out
