Michael 1016a4d2c4 feat(home,sidebar): brand hero + sidebar = footer style + PNG icon
Bundles a handful of UX cleanups:

- Findings-card chevron moved to the LEFT side of the head. CSS still
  rotates it 90° between collapsed/expanded states.

- Tool-link buttons in findings rows (``Clean Text →`` etc.) are now
  left-justified against the icon column with minimal surrounding
  whitespace. Action column ratio dropped from 1.8 → 1.4 and the
  button switched from ``width="stretch"`` (centered text) to
  ``width="content"`` (shrinks to fit, left-aligned within column).

- Home-page hero now mirrors the sidebar brand block: 56px ink "D"
  chip on the left + "UNALOGIX" eyebrow stacked above "DataTools"
  wordmark, then the "Clean. Normalize. Transform." tagline beneath.
  New ``.dt-page-brand / -row / -words / -mark / -eyebrow /
  -wordmark`` rules in ``_DESIGN_TOKENS_CSS``. Streamlit wraps h1
  elements in an emotion-cache div with extra padding; a descendant
  flattener (``.dt-page-brand-words *`` margin:0 / padding:0) keeps
  the eyebrow + wordmark stack the same height as the chip so they
  center-align cleanly.

- Sidebar nav restyled to match the sticky-footer Help/Close buttons
  exactly: 13px / 500 / 1.3 line-height, 5×10px padding, 8px gap
  between icon and label, transparent background. Active item gets
  the same ``rgba(0,0,0,0.04)`` tint as the hover state (no white
  pill, no shadow), only the heavier weight + ink text distinguishes
  it.

- OS app icon (page_icon) switched from SVG to a Pillow-rendered
  ``datatools_icon_256.png`` so Windows / macOS taskbar+dock pick
  it up reliably (some OS shells fall back to a default icon for
  SVG favicons). Rounded-square ink ground with cream "D" centered —
  same mark as the sidebar chip + hero chip.

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
