feat(maintainers): add an interactive globe of maintainer locations - #1493
Added an interactive world map showing maintainers with location information.
Nearby maintainers are grouped into map markers, with counts and tooltips listing member names and available locations.
Marker colors reflect library categories when all maintainers in a group share one category.
Added zoom and pan controls, including a way to focus on a selected maintainer’s location. Wheel zoom requires Ctrl or ⌘; Shift+arrow keys pan.
A status message appears when no maintainers have location information.
TanStack Charts globe
TanStack Charts renders the dotted continents, atmosphere, and location markers. The COBE dependency was removed.
The globe scales and rises inside a fixed drawing surface. The page intro replaces the globe heading and location count. Profiles can float above the globe while staying clear of the page intro, filters, and maintainer list.
On phones, the globe fills both lower corners of the first viewport. Scrolling reveals the full lower edge. When zoomed, the globe can extend upward and fades before the maintainer list.
Connecting lines are limited to 72 px on desktop and 48 px on mobile. In crowded areas, profiles stay available and their lines disappear until a nearby slot opens.
The globe skips redundant startup draws and stops requesting frames when paused and settled or outside the viewport.
The globe and the surfaces around it read their colors from design system tokens, so the dotted continents, atmosphere, location markers, controls, and panels follow light and dark mode without hardcoded values. A five-step cool neutral tint ramp was added for the continents. The videos above still show the earlier blue palette.

Controls and copy
The zoom controls gained a reset button for zoom and tilt, separated from the pause toggle by a design system divider.
The globe controls, filter dropdown, profile chips, and selected cluster panel share one surface and border treatment.
The help text documents every shortcut, including Esc and focus, with keys wrapped in <kbd>.
The selected cluster heading reads the same for one or many maintainers, with a line pointing at GitHub.
The gap between the selected cluster panel and the maintainer list is covered once by the flex gap.
Earlier globe demos
The desktop globe fills the width, starts one zoom step closer, and expands behind the page content without moving it.
Off-screen locations show a small avatar row and count on desktop and mobile. The badges clear as you scroll into the maintainer list.
The globe reuses its profile elements, skips redundant draws during entrance, and stops scheduling frames when it is completely out of view.
The globe starts its entrance sooner and rises farther into view as it scales in. Reduced-motion mode skips the entrance animation.
Profiles and off-screen badges stay clear of the maintainer photo grid. On desktop, the bottom of the globe fades out before the grid.
Both demos start with a page reload and show the globe rotating for about 3.5 seconds before scrolling.
Merging this PR will not cause a version bump for any packages. If these changes should not result in a new version, you're good to go. If these changes should result in a version bump, you need to add a changeset.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The maintainers page now displays located maintainers on a world map. The map groups nearby pins, shows member and location details, and supports zooming and panning. Maintainer records gain optional location data.

Summary
Location data and grouped map pins src/libraries/maintainers.ts, src/components/MaintainersMap.tsx
Maintainer gains an optional location with a name, latitude, and longitude. Maintainer records gain location data. The map projects located maintainers, groups nearby pins, and shows counts and member location details.
Map controls and route integration src/components/MaintainersMap.tsx, src/routes/maintainers.tsx
The map adds zoom, pan, and reset controls, plus an empty-location status message. The maintainers route passes filtered maintainers and selected libraries to the map.

Full details: Title check
Explanation
The title "feat(maintainers): add an interactive globe of maintainer locations" matches the main change. The PR adds MaintainersMap.tsx, which renders maintainers with locations on a world map with pan and zoom. It also adds optional location data to Maintainer records and renders the map on the maintainers route. The title says "globe", but the summary describes a world map with 2D projected positions, pan, and zoom. The title does not mention the map's pan and zoom, but it names the primary change. The commit messages also mention dropping the map subtitle, which the title does not need to cover.
Full details: Docstring Coverage
Explanation
Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 6 functions across 3 files.
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

COBE marker ids make it rewrite :root custom properties and move an anchor
div per marker on every update, which restyles the whole page each frame.
Project marker positions in JS instead (same math as COBE), cache card sizes,
only write card styles when visibility flips, keep the frame loop running
through zoom changes, drop backdrop-blur over the canvas, and delete the
unused land map JSON.
