DataTools is local-first — "Upload" reads like "send data somewhere
remote", which contradicts the product positioning. Sweep replaces
the user-visible term throughout the UI:
- ``src/i18n/packs/en.json`` + ``es.json``: all ``upload.*`` strings
(heading, intro, uploader labels, empty state, switch-back, etc.)
and ``gate.default_name``. The ``intro_multi`` "no upload anywhere"
phrasing dropped the verb entirely — now reads "nothing leaves
this computer".
- All 9 tool pages: ``st.file_uploader(label="Upload …")`` →
``"Import …"``; matching ``st.info("Upload a …")`` empty-state
banners; ``help="Upload …"`` strings on disabled uploaders.
- ``9_Pipeline_Runner`` + ``5_Column_Mapper``: radio-option text
``"Upload schema/pipeline JSON"`` → ``"Import …"`` plus the
``.startswith("Upload")`` branch guards that read those values.
- ``_home.py``: "**Uploaded files**" → "**Imported files**".
- ``app_demo.py``: "Uploaded file is …" → "Imported file is …".
Internal identifiers left untouched: function names
(``pickup_or_upload``, ``_StashedUpload``), session-state keys
(``home_upload``, ``home_uploads``, ``home_uploaded_*``,
``merger_file_upload``), audit-log event category (``"upload"``),
Streamlit testid CSS selectors. None of those are visible to the
user.
The file_uploader's dropzone button text is a baked-in React
literal that Streamlit's ``label=`` doesn't reach; rewritten at the
DOM level with a small ``_RENAME_UPLOAD_BUTTON_JS`` snippet shipped
through ``st.iframe`` (same pattern the sticky footer uses to mount
on ``<body>``). A ``MutationObserver`` on the parent document re-
applies the swap when Streamlit remounts the dropzone after file
add/remove or page navigation, throttled via ``requestAnimationFrame``.
