Prompt

I'm noticing heavy frame drops during scroll transitions in `src/components/ScrollReveal.vue`. Run `/fixing-motion-performance src/components/ScrollReveal.vue` on it and output the audit findings: quote the specific code segments that degrade performance, state briefly why each line is an issue, and supply functional code adjustments to resolve them.

What was checked, without and with the skill
Checked	Without skill	With skill
The explanation for why each quoted violation matters is restricted to a single sentence.	Missed	Passed
The recommended code fixes maintain the existing animation stack without introducing a new motion library.	Passed	Passed

Fix animation performance issues.

how to use

/fixing-motion-performance Apply these constraints to any UI animation work in this conversation.
/fixing-motion-performance <file> Review the file against all rules below and report:
