`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint
were still grading against 3.10 -- three tools judging an interpreter nothing
runs any more, and ruff withholding the pyupgrade fixes that only become safe
at the newer target. `pin_ci_python.py` rewrites exactly these three knobs.
What the stale target was hiding: `datetime.timezone.utc` where `datetime.UTC`
is now correct (UP017), `socket.timeout` where `TimeoutError` is (UP041),
deprecated `typing` imports (UP035), PEP 695 `type` aliases (UP040), and ruff's
stable formatter applying PEP 758 -- `except (A, B):` becomes `except A, B:`.
That last one makes the source 3.14-only at the syntax level, which is what
`requires-python = ">=3.14"` already promised; kuhy chose it deliberately over
holding ruff a release back (2026-08-29).
ruff, ruff-format, mypy --strict and pylint all clean at the new target. The
two modified web/ TypeScript files are another session's in-flight work and
are deliberately left unstaged.

Adds a React/TypeScript frontend (web/) with a Python stdlib HTTP server
backend. The UI mirrors the CLI `stats` command in the browser, with
real-time sliders for ProtonDB rating, HLTB confidence thresholds, daily
play time, per-game time cap, playtime mode, no-HLTB-data fallback, and a
target-date planner. A parity badge confirms the client-side totals
reproduce the CLI defaults exactly (786 / 67031.1h / 143017.2h / 238447.9h).
Python side:
- `_web_dataset.py`: offline projection of HLTB/ProtonDB/snapshot caches
into a compact, secret-free JSON payload; 100% branch coverage
- `_web_server.py`: zero-dependency stdlib HTTP server serving the built
Vite bundle and the /api/dataset endpoint; 100% branch coverage
- `main.py`: new `serve` command wiring
Frontend (Vitest + RTL, 100% branch coverage enforced):
- TypeScript port of ProtonDB compound rating rule with full parity
- Pure client-side filtering via estimate.ts (no server round-trips)
- SVG completion timeline chart, sortable/searchable game table
- Steam dark theme; responsive layout
Pre-commit: adds `vitest-coverage` hook at pre-push stage requiring 100%
branch coverage on the React codebase.
