The Beacon Strings

What it is

Per-instrument dynamic OG image generator at /api/og/strings/[instrument]. Each /strings/[instrument] page (Mark XCIX Tutor) now renders its own dedicated share card on social — names the player + headline + featured 3 famous repertoire pieces — instead of the generic OK card. Edge runtime, ImageResponse, no DB calls (pure render from STRINGS_MARKETING typed catalog). Cache 1h s-maxage + 7d stale-while-revalidate. Sister generator to Mark CVII Beacon Stamp (per-state).
