BIOME — Mother Skill for Platform Descriptors

BIOME n. — a bounded region of an ecosystem, with its own inhabitants and climate, coexisting with sister biomes and exchanging matter, energy, and information with them along defined gateways.

This skill is the mother prototype that platform-descriptor sister skills inherit from. Each daughter biome declares inherits: biome in its CARD.yml / GLANCE.yml / SKILL.md frontmatter, and its directory structure mirrors the skeleton this skill defines.

Six example biomes ship with this skill for reference, each illustrating a distinct dimension:

Biome	Family	What it exemplifies
`biomes/gcp/`	cloud	Canonical cloud hyperscaler
`biomes/aws/`	cloud	Another hyperscaler with distinct vocabulary (accounts, regions, AZs, SSO)
`biomes/azure/`	cloud	A third hyperscaler with enterprise-IT flavor (subscriptions, RGs, Managed Identities)
`biomes/github/`	collaboration	Cross-cutting — forge + CI + social graph + MMPORG + branch-as-object database; touches every other biome
`biomes/tailscale/`	overlay	Cross-cutting — mesh network that threads through every other biome by design
`biomes/cloudflare/`	overlay	Multi-role — CDN + Workers + R2 + DNS + Tunnels + Pages; the "many simultaneous roles" lesson

Consumer repos adopt this skill and populate their own biomes/registry.yml + biomes/gateways.yml + per-biome daughter skills in their own repos. The example biomes here are vendor-neutral reference material, not a working registry.
