the layout skeleton is officially complete now that style.css is implemented. i went for a dark, high-contrast, brutalist terminal look to match the puzzle theme.

here are the key UI updates:

• custom scrollbar: added a minimal 4px scrollbar to the rules list so it blends perfectly into the sidebar
• unlock animations: handled the transitions for .rule-item. when a rule becomes visible, it smoothly fades in and slides up into place using transform: translateY(6px) to 0.
• editor grid algnment: synced the code canvas layout, line numbers, and preview panels so the split-view remains perfectly aligned across different workspace sizes.

the interface looks clean now, so next up i’m wiring the actual parser and the rule engine in script.js to make it work. :3
