Quality deployment solutions — dotfiles, configuration, and release tooling that carry a project from first checkout to production.
The Model Context Protocol session every MCP server on this page speaks: initialize, tools/list, tools/call — JSON-RPC 2.0 envelopes over stdio.Lumen's shipped grade presets applied to one portrait crop by the engine itself — the before/after board from the 2026-10-18 lightshow video study, produced with the engine's own style operations.The demo_toon preset — landed as a shipped style on 2026-10-18 — checked on a pixel sprite from the same study: the posterize step that speckles painted portraits stays clean on pixel art.
Measured on primo (13th Gen Intel Core i7-13620H) with Lumen's release build, timing lumen::style::grade_image — the pixel path behind the style_apply MCP tool — at strength 1.0: 20 timed runs per row after 3 warm-ups, the median reported; PNG decode/encode and the per-run input clone sit outside the timed region. The subject is the 448×448 Séraphine portrait crop from the 2026-10-18 Lumen study, and that crop upscaled to 1024×1024. Throughput counts input megapixels per second. Raw record: run_lumen_bench.py and lumen-results.json in the site-bench-20261018 work record.
