Add partner / integration logo set (#9)

A namespace of third-party tool marks (GitHub, Google, Notion, Asana,
Slack, Claude, HubSpot, 1Password, Ramp) for integration/tools surfaces —
sourced from OFFICIAL brand resources (GitHub_Logos.zip, Ramp production
SVG, Google 4-color G artwork) or CC0 Simple Icons glyphs for monochrome
icons. Nothing redrawn.

These are the trademarks of their owners, used nominatively — NOT
OpenMined assets and NOT governed by OMDS tokens. partners.json is the
source of truth (owner, official source, variants, brand color, gaps);
README.md carries the governance (never recolor where forbidden, never
imply endorsement, source officially or leave a documented gap).

Per brand: icon.svg (monochrome, fill=currentColor — inline + set color
to theme), icon-color.svg (official brand color), logo*.svg (wordmark
lockups where officially available — GitHub black/white, Ramp). A
PartnerLogo.astro atom renders them, and a "Partner marks" styleguide
section displays the set. Documented gaps pending official files:
Rippling (Drive-gated), Slack's 4-color icon, and several lockups.

+## Partner / integration marks (`public/logos/partners/`)
+
+Third-party tool logos (GitHub, Slack, Notion, Asana, Claude, HubSpot, 1Password, Google, Ramp, …) used to identify integrations — **NOT OpenMined brand assets, and NOT governed by OMDS.** Each is the **trademark of its owner**, used nominatively. Rules:
+
+- **Never recolor/restyle** a mark where the owner forbids it (e.g. Google's 4-color G stays as-is). OMDS color tokens do **not** apply to partner marks. Never imply endorsement.
+- **Never redraw** a partner mark — source it from the owner's official brand resources (or a CC0 Simple Icons glyph for monochrome icons), or leave it as a documented gap.
+- `partners.json` is the source of truth: per brand it records trademark owner, official source URL, available variants, brand color, and known gaps. `README.md` carries the governance.
+- Per brand: `icon.svg` (monochrome, `fill="currentColor"` — inline + set `color` to theme it), `icon-color.svg` (official brand color), `logo*.svg` (wordmark lockups where officially available). The `PartnerLogo.astro` atom renders them.

+# Partner / integration marks
+
+Third-party tool logos used to identify integrations — **not** OpenMined brand
+assets. Each mark is the **trademark of its owner** and is used nominatively
+(to refer to the product). They are governed by each owner's brand guidelines,
+**not** by OMDS:
+
+- **Never recolor or restyle** a mark where the owner forbids it (e.g. Google's
+  4-color G must stay as-is). OMDS color tokens do **not** apply here.
+- **Never imply endorsement or partnership** that doesn't exist.
+- Some owners (Google, HubSpot, Slack, GitHub) require permission for certain
+  uses — confirm the surface is referential before shipping externally.
+
+## Files (per brand, see `partners.json` for the full record)
+
+- `icon.svg` — monochrome glyph, `fill="currentColor"`. Inline it and set `color`
+  to theme it (mono / "1-color"). As an `<img>` it renders black.
+- `icon-color.svg` — the mark in its **official brand color** (or full color for
+  multicolor marks like Google's G). Use via `<img>`; do not recolor.
+- `logo-*.svg` / `logo.svg` — full wordmark lockups where officially available
+  (currently GitHub black/white, Ramp).
+
+`partners.json` is the source of truth: per brand it records the trademark owner,
+official source URL, available variants, brand color, and known **gaps** (marks
+that still need an official file dropped in — e.g. Rippling, Slack's 4-color icon,
+several wordmark lockups behind brand-kit gates).
+
+## Source
+
+Lockups/marks are official (GitHub `GitHub_Logos.zip`, Ramp production SVG,
+Google 4-color G artwork). Monochrome glyphs for single-color icons come from
+[Simple Icons](https://simpleicons.org) (CC0 file license; trademarks remain the
+owners'). Never redraw a mark — source it officially or leave it as a documented
+gap.
