Stack Glint: Tile Cascades First Launch Foundation Sprint 01

Stack Glint now has a verified first-launch foundation for Campaign Level 1, First Spark.

Stack Glint: Tile Cascades now has its Sprint 01 first-launch foundation on main.

The sprint converts the imported redesign package into executable production material for Campaign Level 1, First Spark: VeritySpec records, structured content data, deterministic validation, C# runtime contracts, tests, roadmap updates, and an evidence ledger.

The first-launch contract covers a compact 5x7 tutorial board, four active colors, one highlighted column, a scripted Ruby drop, a Ruby group clear, an Azure gravity cascade, three-star settlement, full-column rejection, local settings and progress, support, privacy, restore visibility, and explicit no-service guardrails.

The merged game PR is Jason-Furr/stack-glint-tile-cascades#4, closing issue #3 with merge commit 7965257. Main checks passed for CI 28612320495, Content Validation 28612320446, VeritySpec 28612320520, and CodeQL 28612328387 plus 28612320070.
