Set up project skeleton and tooling for MIL-001

Add pyproject.toml (Python >=3.13, no runtime dependencies, pytest, ruff
and mypy as dev extras), a Doxyfile that scans src/, the
src/coffee_machine package with stub constants and main modules, and a
pytest smoke test. Ignore Doxygen output in .gitignore.

+# Artifact Registry
+
+This project's artifact state. Types, short names and `CrossReference
+Candidates` come from the framework catalog
+(`framework/registry/artifact-catalog.md`); this file only records where
+each document lives in *this* project and the next version to use.
+
+Delete rows for types you don't use. Add a row the first time you create a
+document of a type. `Primary File` may contain a glob (e.g.
+`docs/uc-*/uc.md`); `framework/scripts/find-crossreferences.sh` reads it.
+
+| Short Name | Artifact Type | Primary File | Next Available Version |

+| MIL | Milestone / Gateway | docs/milestones/*.md | 004 |
+
+## Languages
+
+Set the PO language when the project starts; `project-planning` asks for it
+if it is missing. A translated artifact is named `<artifact>.<language>.md`
+(for example `business-case.da.md`); the English file stays the source.

+## Notes
+
+- "Next Available Version" is the zero-padded (3-digit) version to use the
+  *next* time a new document of that type is created. Increment it only when
+  a brand-new document is created, not when an existing document's
+  `## Version History` gets a row.
+- `ADR` uses 4 digits (`0001`); `RC` is sequential across all artifact types.

+
+## Executive Summary
+
+Build a console coffee machine in Python as the Day 15 assignment of Udemy's
+"100 Days of Code: The Complete Python Pro Bootcamp". The program serves
+espresso, latte and cappuccino, accepts US coins, tracks water, milk and coffee
+and prints a report on request. It is published as a readable, runnable
+reference for other course participants and as a portfolio piece.
+
+## Methodological and Standards Foundation
+
+Planning follows the SQA/QC framework mounted at `framework/` (plan first, then
+code). Quality is described with ISO/IEC 25010:2023 characteristics. Code uses
+the `coding-conventions` skill and Doxygen comments.
+
+## Problem Statement
+
+The assignment specification is long and detail-heavy (resources, coins,
+refunds, change). Solutions shared by participants vary widely in structure and
+readability, and a single `main.py` script is hard to test.
+
+## Business Opportunity
+
+A small, well-structured and tested solution is a clear example for other
+participants and for viewers browsing the repository.
+
+## Objectives
+
+1. Implement the full assignment behaviour: `report`, `off`, drink selection, resource check, coin processing, change, profit.
+2. Keep the assignment's function names so participants can compare solutions.
+3. Cover the behaviour with automated pytest tests.
+4. Document how to set up a local `.venv` and run the program and tests.
+5. Publish the repository with a description, topics and README.
+
+## Scope
+
+### In Scope
+
+- Console program under `src/` with a `constants.py` for menu, coins and starting resources.
+- pytest tests under `tests/`.
+- `pyproject.toml`, Python `.gitignore`, `Doxyfile`, `README.md`.
+- Project documents under `docs/`.
+- Repository description and topics on the git host.
+
+### Out of Scope
+
+- Graphical or web interface.
+- Payment other than the four US coins.
+- Persistence of resources or profit between runs.
+- Runtime dependencies.
+
+## Expected Benefits
+
+### Tangible Benefits
+
+- Completed Day 15 assignment.
+- Runnable code with tests and setup instructions.
+
+### Intangible Benefits
+
+- Practice with planning, testing and Python project layout.
+- A reusable template for later course projects.
+
+## Strategic Alignment
+
+Supports the learner's goal of finishing the 100 Days of Code course with
+professional project hygiene, and the goal of sharing readable solutions.
+
+## Success Criteria
+
+| # | Criterion | Target | Measure |
+| --- | --- | --- | --- |
+| 1 | Assignment behaviours implemented | 100% of listed behaviours | Manual run against the specification |
+| 2 | Tests pass | All pytest tests green | `python -m pytest` |
+| 3 | Runtime dependencies | 0 | `pyproject.toml` `dependencies` is empty |
+| 4 | Setup documented | A new reader can run program and tests from README | README walkthrough |
+| 5 | Repository metadata | Description and at least 3 topics set | Repository page |
+
+## Risks
+
+| Risk | Impact | Mitigation |
+| --- | --- | --- |
+| Floating-point rounding in coin totals | Wrong change or refund | Compute money in cents (integers) internally |
+| Token in `.env` leaks | Account compromise | `.env` is gitignored, never imported or tested by the project |
+| Scope creep beyond the assignment | Delay | Out of Scope list above |
+
+## Assumptions
+
+- Python 3.13 or newer is installed.
+- The git host repository already exists and is reachable.
+
+## Constraints
+
+- Python greater than 3.13 as requested, `venv` for environments, pytest for tests.
+- Constants live in `constants.py`.
+- Source files use Doxygen comments.
+- Nothing is committed or pushed unless the user asks.
+
+## Cost–Benefit Assessment
+
+| Costs | Benefits |
+| --- | --- |
+| A few hours of the learner's time | Finished, tested, shareable assignment (qualitative; no money involved) |
+
+## Stakeholders
+
+| Stakeholder ID (SA) | Interest in this project |
+| --- | --- |
+| S01 | Completes the assignment and owns the plan, code and review |
+| S02 | Reads and runs the code, compares solutions |
+| S03 | Browses the repository for ideas |
+
+## Recommendation
+
+Proceed — the scope is small, well specified and delivers a reusable example.

+- Week 1 starts 2026-10-05; the plan ends by 2026-10-12.
+- Phase length: two to three days; S01 reviews each phase through a pull request (see [SA-001]).
+- Each phase is one branch and one pull request.

+
+## Plan Risks
+
+| Risk | Impact | Mitigation |
+| --- | --- | --- |
+| README template not supplied | README task blocked | Ask S01 for the template before the task |
+| Doxygen not installed locally | Cannot verify docs | Document the install step in README |
+
+## Open Issues
+
+- The README template referenced in the request ("template below") was not included.
+- No use cases or user stories are written; tasks are plain technical tasks implementing the assignment specification. S01 can ask for a use case ("Order a drink") if wanted.
+- Python ">3.13" is read as 3.13 or newer (`>=3.13`).

+## Purpose
+
+Identify who is affected by the coffee machine project and what each needs,
+using a power/interest grid (Manage Closely, Keep Satisfied, Keep Informed,
+Monitor).
+
+## Stakeholder Summary Table
+
+| ID | Name | Role/Title | Organization | Power Level | Interest Level | Quadrant | Primary Concern (Business Language) |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| S01 | Jens Tirsvad Nielsen | Course participant: Product Owner, developer and reviewer | Self | High | High | Manage Closely | Finish the assignment correctly with clean structure |
+| S02 | Udemy coursists | Fellow course participants | Udemy course community | Low | High | Keep Informed | Readable, runnable code with the assignment's function names, and README run instructions |
+| S03 | GitHub viewers | Repository browsers | Public | Low | Low | Monitor | A clear repository description, topics and README, and no runtime dependencies |
+
+## Power/Interest Classification Rationale
+
+- **Manage Closely (S01):** decides scope, writes and reviews everything.
+- **Keep Informed (S02):** cannot change the project but depend on its clarity.
+- **Monitor (S03):** casual visitors; a good first impression is enough.

+| S01 | Correct behaviour per specification | Functionality |
+| S01 | Tested and maintainable | Supportability |
+| S02 | Easy to read and run | Usability |
+| S02 | Same function names as the assignment | Functionality |
+| S03 | Quick understanding of the repository | Usability |
+| S03 | No dependencies to install | Implementation (+) |

+| --- | --- |
+| S02 want assignment-style function names; S01 wants testable structure | Keep the assignment's names (`is_resource_sufficient`, `process_coins`, `is_transaction_successful`, `make_coffee`) and make them pure/parameterised so they are testable |

+| Stakeholder | Goal / use case | Business Case objective |

+| S02 | Read and run the code | [BC-001] objectives 2, 4 |
+| S03 | Browse the repository | [BC-001] objective 5 |
