What

• pyproject.toml: requires-python = ">=3.12"; classifiers are Python :: 3 and Python :: 3.12 only; mypy python_version = "3.12"; ruff target-version = "py312".
• README Requirements line and the ARCHITECTURE.md technology table now say Python 3.12+.
• CHANGELOG [Unreleased] entry.
• Test: tests/test_dependency_declarations.py::test_python_floor_is_3_12_everywhere_pyproject_states_it reads pyproject.toml with tomllib and asserts the four values (red before the change, green after).
• Ruff's py312 target adds findings. In tests/ they are fixed mechanically (UP006/UP017/UP035, zip(strict=True) where the lengths are asserted equal, import order; 94 changed lines in total with the rest of the PR). In seo_manager/ they would be about 1,400 changed lines, over the diff cap, so [tool.ruff.lint.per-file-ignores] ignores those seven rules for seo_manager/** with a comment. A follow-up ruff check --fix PR removes the entry.

Why

>=3.8 was false: the code uses tuple[...] annotations and zoneinfo, and CI tests 3.12 only. JP decided on 2026-10-24 (D1) on >=3.12, so no 3.10 floor job and no CI change.

Not touched: [project.scripts], anything blog/twitter (#43, #44).
