Now I'll install Framer Motion and create a much improved version with a vertical line indicator and sparks emanating from it:

I've completely redesigned the RSI Momentum Bar with Framer Motion. Key improvements:

Line Indicator (replacing the circle):

• Vertical line with rounded caps that extends above and below the bar
• Pulsing glow animation in extreme zones that intensifies with RSI proximity to 0/100
• Subtle height breathing animation and shake effect at high intensity

Spark System (now from the line):

• Sparks emanate from the line position with a wide upward spread using custom cubic-bezier easing for an explosive feel
• Multiple color variations per zone (5 shades for green/red) for visual richness
• Spark count and distance scale with intensity
• Energy wave rings pulse outward from the line in extreme zones

Smooth Animations:

• Spring physics for the indicator position using useSpring
• Stretch/squash effect on the line based on movement direction
• Intensity meter in the tooltip with animated bars
• Border glow on the tooltip panel when in extreme zones

I've simplified the component significantly for a more professional look. The indicator is now just a clean vertical line that stays within the bar margins (same height as the bar). Removed all the pulse animations, energy waves, breathing effects, and extra caps from the line. The sparks now originate from random points along the line height and spread upward with a smooth custom easing curve. The glow on the line only appears subtly in extreme zones based on intensity.
