Smoother, more modern motion across Strata, built on graphite-ui 1.2.0 (Project-Graphite/graphite-ui#24). No new dependency. Everything is off under prefers-reduced-motion: reduce.

• graphite-ui 1.2.0: brings sliding sidebar and phone tab bar highlights, a tab underline that morphs between pages, a header border that appears on scroll, menus and popovers that grow from their anchor, dialogs and snackbars that rise in, press feedback on buttons, a pop on checkboxes, and smooth <details>. List rows fade in.
• Page changes: Shell wraps the routed page in PageTransition, so the old page fades out while the new one plays its page-enter rise. CrashBoundary no longer needs key={pathname}, because the keyed transition remounts it. ScrollToTop is a layout effect, so the new page is captured at the top.
• Tasks: the strike-through draws across the title when a task is done.
• Habits: the check fills in. A check by the user plays a pop and a ring; already-checked habits don't animate on load.
• Settings → Apps: the tile check fills in smoothly.
• Spending overview: stats count smoothly to the new values when the period changes (<Amount tween>). The first render shows the final value, so the swap from skeleton stays seamless.
• Signed-out home page: the feature cards come in one after another and get a hover border.

Checked on a dev server against the local stack: the view transition, tab underline morph, sidebar and 390px tab bar slides, header, menu, dialog, palette, snackbar, task strike-through and habit animations. Lint and the frontend build pass.

Not seen working in the browser: the task checkbox pop on a real completion and the spending tween, because the local backend went down mid-check.
