Slow and reverse hero neon scan animation

[Gonza10V]

Motivation

• Reduce the intensity/flicker of the hero neon effect and change its motion to better match the intended visual direction.

Description

• Change the .hero-neon-text--active animation from 2.4s var(--ease-out) 2 to 7.2s linear 2 to slow the scan and use a linear timing function.
• Reverse the @keyframes hero-neon-scan background-position endpoints so the scan now moves from 120% to -120% instead of the opposite direction.
• Preserve existing filter and will-change properties to maintain the neon glow behavior.

Testing

• Ran stylelint against the CSS and it completed without errors.
• Ran npm test (project unit tests) and all tests passed.
• Performed a local build with npm run build and it finished successfully.
