Okay but has anyone actually pushed this setup into the deep end? Because I spent a full day on the frontend article editing dark theme — JCE toolbar colours, the calendar widget, accordion tabs, Choices.js dropdowns, MFA method cards — and Claude Code tracked every single selector across the whole session without losing the thread.
I described the problem out loud: 'the calendar day cells have a white background when selected'. It wrote the correct `--calendar-bg` CSS variable override. It knew which tokens to use because the training file told it the colour system — violet for authority, cyan for data, emerald for code. It reasoned within the system instead of guessing.
If you're even slightly into design this workflow will break your brain in the best way. Get the Kit, get a Claude.ai subscription with enough context, and give yourself an afternoon. You won't go back.
