Capstone: start
Pipeline: mockup -> logic -> uiux -> architecture -> standards -> stack -> build.
From this skill's base directory, read ../core/references/core.md
(this command routes rather than writes, so core-authoring.md is not
needed), then execute
../core/references/protocols/start.md
exactly.
Always ask subagents or inline at the start of each run, including resumes. Wait for the explicit choice and carry it through the whole pipeline, including research, readback and build.
