config-presets — Ready-made operation stacks

Each config_presets/*.json file is a ready-to-run operation stack: a JSON array of operations applied to a stage in order. Use one to get a known-good baseline before considering custom tuning.

What this skill covers

• Preset table — the six presets, their effect, and whether they are lossless.
• Step 1 — pick a preset for the user's goal.
• Step 2 — run the preset.
• Step 3 — customize if needed.

Companion skills: run-operations (CLI usage, flags, error handling), tune-parameters (iterate a single operation's parameters after running a preset).
