Changelog - 2025-12-09 (#1)

Implemented the first version of the Dark Matter team page following the shared TeamPagesSpecification.md pattern, including:

A data-driven team model (TeamMember) backed by JSON content.
Role-based spans for Managing Partners and Founding Team.
A simplified but theme-aware PersonCard component.
New inline SVG social icons (LinkedIn, GitHub, Instagram, Medium, Substack, X) that inherit the surrounding text color.

This gives Dark Matter a reusable team presentation pattern aligned with Hypernova/TWF, but styled for the Matter theme.

Changes by Area

Added src/types/team.ts:
- Defines SocialLink, TeamMember, TeamSectionProps, and a TeamRole union.
- Mirrors the Hypernova/TWF shape so future sites can reuse utilities.
Created src/content/people/team.json as the initial Dark Matter team source of truth:
- Seeded entries for Mark Moline, Skinner Layne, Michael Staton, and Thomas Vu.
- Included classifiers values such as "Managing Partner, Team" and "Founding Partner, Team" to drive role grouping.
- Added social links (LinkedIn, X, GitHub, Medium) using a { name, href, icon } structure compatible with SocialIcons.

Implemented src/pages/team.astro:
- Imports team.json as TeamMember[].
- Implements a groupByRole helper that:
  - Normalizes classifiers to an array.
  - Uses a classifierMap to map values like "Managing Partner", "Founding Principal", and "Founding Partner" into internal buckets (managingPartners, foundingTeam).
  - Ensures each person appears in exactly one primary span on the page.
- Computes groupedTeamData and passes the buckets into span components.
Current spans rendered on /team:
- ManagingPartnersSpan → Mark.
- FoundingTeamSpan → Skinner, Michael, Thomas (all Founding Partner-classified profiles).

Added src/layouts/TeamLayout.astro:
- Wraps team content in BaseThemeLayout.
- Provides a centered main container (max-w-5xl) with a responsive grid (grid-cols-1 → md:grid-cols-2).
- Sets sensible defaults for <title> / description (Our Team | Dark Matter).
Added span components in src/components/team/:
- ManagingPartnersSpan.astro
- FoundingTeamSpan.astro
Shared characteristics:
- Import a common team-spans.css stylesheet.
- Render a role header (<h1 class="role-header">…</h1>) and a .person-cards container of PersonCard instances.

Created src/components/team/PersonCard.astro:
- Displays:
  - Square image (lazy-loaded) with hover scale.
  - Name + role centered.
  - Truncated bio (word-based, with a line clamp) to keep cards compact.
  - Optional social icons row at the bottom.
- Uses Matter theme tokens for background, border, and text colors.
Fixed card height behavior to avoid “cards into the abyss”:
- Removed h-64 and h-full style constraints from the card body so height is driven by content rather than a fixed 16rem block.
- Replaced flex-1 + mt-auto layout with a simpler column stack so the social row sits snugly under the bio.
- Result: all cards shrink-wrap more closely to their content while preserving consistent styling.

Added src/styles/team-spans.css tuned for Dark Matter:
- .team-span uses full width and break-inside: avoid so role groups stay contiguous.
- .role-header uses a gradient from var(--color-accent) to var(--color-foreground) with a left border and underline, matching the Matter theme.
- .person-cards uses display: contents so the outer grid controls layout.

Added SVG assets under public/icons/:
- linkedin.svg
- github.svg
- instagram.svg
- medium.svg
- substack.svg
Updated src/components/ui/SocialIcons.astro:
- Accepts socialLinks: { name, href, icon? }[] and an iconSize prop.
- Normalizes the platform via (link.icon || link.name).toLowerCase().
- Renders inline SVG icons for:
  - linkedin
  - github
  - instagram
  - medium
  - substack
  - x / twitter (X logo path)
- All icons use currentColor for both fill and stroke so they automatically inherit the link’s text color and theme hover states.
- Maintains existing pill-style button chrome (border, subtle background, hover transitions).
Updated PersonCard.astro SocialPlatform union to include medium and x so TypeScript recognises these platforms when mapping social links.

src/types/team.ts — shared TeamMember/TeamRole/SocialLink definitions for Dark Matter.
src/content/people/team.json — initial Dark Matter team roster and metadata.
src/layouts/TeamLayout.astro — team-specific layout wrapper reusing the Matter theme shell.
src/styles/team-spans.css — shared span styles (role headers, container behavior) for the team page.
src/components/team/PersonCard.astro — reusable team member card.
src/components/team/ManagingPartnersSpan.astro — span component for managing partners.
src/components/team/FoundingTeamSpan.astro — span component for founding team members.
public/icons/linkedin.svg — LinkedIn icon.
public/icons/github.svg — GitHub icon.
public/icons/instagram.svg — Instagram icon.
public/icons/medium.svg — Medium icon.
public/icons/substack.svg — Substack icon.

src/components/ui/SocialIcons.astro — now renders inline SVG icons for common platforms using currentColor and supports x/twitter.
src/components/team/PersonCard.astro — updated layout to be content-height driven and expanded social platform support (medium, x).
src/pages/team.astro — added groupByRole helper, wired spans, and mapped classifiers (Managing Partner, Founding Partner, Founding Principal, Founding Team) to internal buckets.

The current role taxonomy covers Managing Partners and Founding Team; additional spans (e.g., Advisory Board, Fellows) can be added later using the same pattern.
Team content is still placeholder text; bios, roles, and images should be revised with real copy before launch.
Once stabilized, the Dark Matter implementation can be used as a reference for extracting a shared @knots/team-patterns package.
