Michael b0ee65e922 feat(ui): warm editorial redesign — Fraunces + Geist + stone palette
Lifts ideas from the ``datatools_layout_redesign.html`` mockup
(artistic licence, not literal). Two changes:

1. ``.streamlit/config.toml`` ``[theme]`` block — cream paper bg
   (#fafaf7), warm sidebar (#f5f4ef), stone ink (#1c1917), burnt
   orange primary (#c2410c). Streamlit threads these through its
   chrome (focus rings, file-uploader accents, link colors).

2. ``_DESIGN_TOKENS_CSS`` injected by ``hide_streamlit_chrome`` on
   every page. Imports Fraunces (display serif), Geist (body sans),
   Geist Mono. Restyles, scoped through ``--dt-*`` custom properties:

   - Page surface + sidebar — warm cream backgrounds, soft warm
     borders, no harsh white.
   - Sidebar nav — section labels in tiny uppercase tracking, nav
     items with soft hover, active item as a white pill with subtle
     shadow.
   - Typography — H1/H2/H3 in Fraunces with tightened tracking;
     body Geist; inline code Geist Mono with orange-on-cream chip.
   - Buttons — primary = dark ink (``#1c1917``) with white text;
     secondary = paper surface with warm border; disabled = muted
     cream.
   - Containers / expanders — editorial cards: 14px radius, 1px
     warm border, faint shadow, warm-cream summary headers.
   - File uploader — cream dropzone with dashed border + per-file
     paper chips.
   - Alerts — soft tinted fills (info=sky, success=mint, warn=amber,
     error=rose) over the kind-specific palette.
   - Inputs, tabs, dataframes — paper surfaces with rounded warm
     borders.

Verified at 1920x1050 + 1400x900 on home page (empty + with file
uploaded + with findings rendered) and Clean Text tool page; no
regressions in the white-bar fix from 65b663b.

Download (non-technical users)

Pre-built installers — no Python required:

Platform Download First-launch note
macOS DataTools-X.Y.Z-mac.dmg Drag DataTools.app into /Applications, then double-click.
Windows DataTools-X.Y.Z-win-setup.exe Run the installer; launches from Start Menu.
Linux DataTools-X.Y.Z-linux-x86_64.AppImage chmod +x the file, then double-click.

Latest release: see GitHub Releases (or the Gumroad listing). The installers are ~150200 MB; the launcher boots a local server at http://127.0.0.1:8501 and opens your browser. Nothing is sent to the cloud.

Install from source (developers)

pip install -r requirements.txt

Python 3.10+ required.

Run

GUI (recommended):

streamlit run src/gui/app.py

CLI — seven entry points:

python -m src.cli            customers.csv [--apply]   # dedup
python -m src.cli_text_clean messy.csv     [--apply]   # text clean
python -m src.cli_format     intl.csv      [--apply]   # format standardize (auto-streams >100 MB)
python -m src.cli_missing    holes.csv     [--apply]   # missing values
python -m src.cli_column_map vendor.csv    [--apply]   # column mapper
python -m src.cli_pipeline   any_file.csv  [--apply]   # chain tools end-to-end
python -m src.cli_analyze    any_file.csv  [--json]    # scan only

Every CLI runs preview-only by default; add --apply to write output.

Language

The GUI sidebar has a language picker. Packs ship for English and Español (src/i18n/packs/); the choice persists for the session. Adding a language: drop a <code>.json next to en.json mirroring its key tree, then list it in LANGUAGES. See Developer Guide §i18n.

Review & Normalize gate

Every uploaded file passes through a CSV-normalization gate before any tool sees it. The analyzer flags ~15 issue types (whitespace, NBSP / zero-width chars, BOM, encoding, smart punct, dirty headers, null sentinels, mojibake, …) tagged by confidence (high / medium / low) and fix action. The GUI shows each finding with Auto-fix / Skip / Customize, a live before/after preview, and an encoding-override picker. Tool pages refuse to load until the gate passes.

Output

Every run writes:

  • {input}_<tool>.csv — the cleaned data
  • {input}_changes.csv (text cleaner) or {input}_match_groups.csv (dedup) — audit trail
  • logs/<tool>_YYYYMMDD_HHMMSS.log — debug-level run log

Original input file is never modified.

Dependencies
