Let me read the relevant UI components I'll use.
Now I have a thorough understanding of the codebase. Let me set up the task list and start building.
Let me start with the fonts and layout setup.
Now let me update the globals.css to use the warm stone palette and the right design tokens:
Now let me create the seed data and types:
Now let me build the Overview layer components:
Now let me build the Participant Detail layer:
Now the Extrapolate Data layer:
Now let me wire everything together in the main page:
The Study Population Tracker for ResearchOS is fully built. It implements all three navigable layers — Overview with stat cards, filter pills, blocks/table toggle, and group cards showing enrollment progress with per-participant visit squares; Participant Detail with a visit timeline, documentation tab with status icons, notes with a textarea input, and raw data download; and Extrapolate Data with three scope modes (by group, by participant, all) including checkbox-driven field selection and export buttons. The design follows the warm stone palette with Source Serif 4 for headings, monospace for IDs, semantic color badges for groups (blue/amber/violet), and status indicators (emerald/amber/stone), all on a clean white-card-on-stone-50 layout with 1px borders and no shadows.
Let me explore the current codebase to understand the data model and UI structure before planning.
Now let me read the remaining components and check available UI components:
Good - I have dialog.tsx, input.tsx, label.tsx, select.tsx, textarea.tsx, and button.tsx available. Let me read the key ones for the forms:
Now I have a thorough understanding of the entire codebase. Let me ask a clarifying question before writing the plan.
The code returns the following error:
A tree hydrated but some attributes of the server rendered HTML didn't match the client properties. This won't be patched up. This can happen if a SSR-ed Client Component used:
- A server/client branch `if (typeof window !== 'undefined')`.
- Variable input such as `Date.now()` or `Math.random()` which changes each time it's called.
- Date formatting in a user's locale which doesn't match the server.
- External changing data without sending a snapshot of it along with the HTML.
- Invalid HTML tag nesting.
It can also happen if the client has a browser extension installed which messes with the HTML before React loaded.
