Overview

Builds Source instances by joining a SourceConfig (block → font mapping) with a Database (block name → codepoint range).

This is the single place that knows how to turn configuration + UCD metadata into live Source objects. Keeping that knowledge out of SourceConfig (which is a pure data loader) and out of Resolver (which is a pure orchestrator) keeps each class's responsibility narrow.

For each block with at least one Tier 1 source in the config, the builder resolves the block's codepoint range from the UCD database and constructs one Ucode::Glyphs::Sources::Tier1RealFont per configured Models::GlyphSource. Blocks in the config that aren't in the UCD database are silently skipped — they may be future blocks or typos, and either way there's no range to serve.
