scale-[0.94] shrinks proportionally — on wide viewports this produced visibly larger horizontal gaps than vertical ones when the sidebar opens, and it left the text engine measuring the un-scaled width (causing the thumb-to-character morph boundary to drift). Switch to outer-container padding (p-6 when sidebar is open on desktop) so the paper inherits an equal pixel inset on all four sides. The ResizeObserver picks up the new dimensions and the layout engine re-wraps text at the actual rendered width.

$app/,$shared/,$features/,$entities/,$widgets/,$routes/ - Components: PascalCase (e.g.,
ComparisonSlider.svelte) - Formatting: 100 char line width, 4-space indent, single quotes

Architecture Notes
This project follows the Feature-Sliced Design (FSD) methodology for clean separation of concerns. The application uses Svelte 5's new runes system ($state, $derived, $effect) for reactive state management.
