# Resource library design update

Updated `/algebra-1/resources` and its shared curriculum/guide layouts.

- New editorial hero, original quadratic illustration and live course counts.
- Unit navigation, searchable lesson cards, collapsible units, completion filters and saved-student selection.
- Existing study-guide links and featured resource retained in a quieter supporting section.
- Lesson contents sidebar, mobile section menu, readable paper layout, vocabulary grid and clearer examples/practice styling.
- Coordinated legacy guide headers and typography, scoped to Algebra routes.
- Brand header/footer, lesson data, assessment APIs, metadata and canonical URLs retained. Collection and breadcrumb structured data included.
- Narrow-screen layouts, keyboard focus styles, reduced-motion rules and print adjustments implemented.

Verification: scoped ESLint and TypeScript pass. The hub, linear lesson, quadratic lesson and legacy STAAR guide return HTTP 200. CSS assets return HTTP 200; lesson section targets, structured data and private-solution omission were checked.

Visual limitation: the in-app browser backend is unavailable. Desktop automation did not provide reliable browser input/capture. No visual or mobile browser verification is claimed.
