seo: expand Organization JSON-LD sameAs to all 10 social profiles

[VaultSparkStudios]

What changed

The Organization JSON-LD structured data block in index.html previously declared only 2 social profiles in sameAs (Discord + GitHub). The footer already carries 14 social channels with rel="me", and the canonical /.well-known/entity-graph.json declares 8. This mismatch means search engines and AI answer engines see an incomplete entity record for VaultSpark Studios on the most-crawled page.

Changes to index.html (head block only):

Field	Before	After
@id	(absent)	https://vaultsparkstudios.com/#organization
legalName	(absent)	"VaultSpark Studios LLC"
sameAs count	2	10

The 10 sameAs entries now match the entity-graph.json canonical source plus Discord and Threads, which carry rel="me" in the footer but were absent from both schema sources:

• GitHub, YouTube, X/Twitter, Instagram, Reddit, Bluesky, Facebook, TikTok, Discord, Threads

The @id anchor (#organization) explicitly links this block to the entity-graph.json @graph node, enabling proper cross-document entity resolution.

Why it matters

• Google/Bing knowledge graph uses sameAs + @id to build entity cards. Incomplete sameAs = fragmented entity signals across 10 separate crawled profiles that don't resolve to a single studio record.
• AI answer engines (SGE, Perplexity, ChatGPT Browse) synthesize social profiles for studio cards. Only GitHub and Discord being wired meant 8 official channels were invisible at the schema layer.
• legalName surfaces in rich result eligibility for organization panels.
• Aligns with CANON-048 (dual-audience — built for Humans AND AI Agents).

What to verify

• Run the page through Google Rich Results Test — Organization entity should show 10 sameAs URLs and both name/legalName
• Validate with Schema.org validator — no errors expected
• Confirm @id resolves: /.well-known/entity-graph.json already uses the same #organization anchor
• No visual or functional change on the page — this is head-only metadata

Scope

Single file change: index.html head block (JSON-LD only). No HTML structure, no CSS, no JS touched.
