Stacks a Colab-like JupyterLab and Studio experience on top of the
existing Blackwell image. Additive only: the training stack, CUDA/torch
pinning, and the Studio/JupyterLab/sshd service trio are unchanged.
JupyterLab labextension (prebuilt in a throwaway builder stage, so the
runtime image stays Node-free):
- Unsloth Dark (Monokai) theme, adaptive light/dark by system preference
- Colab-style ArrowDown/Up cell navigation
- top-bar Unsloth logo (stock Jupyter logo disabled and locked)
- #@title lines render as collapsible Heading-2 form bars
- Ctrl+A in a cell output selects only that output, not the whole
notebook (the old behaviour ran notebook:select-all and was laggy)
- right activity bar hidden by default
- overrides.json: per-cell run button without auto-advance, labeled
Restart and Run All, windowing off so collapsing an output does not
snap to the cell top, news/update prompts suppressed
Studio and login branding: Unsloth favicon, page logo, and a dark
Unsloth login page that rotates through the curated Studio sloth
stickers (fail-soft to the logo).
Notebook organization and Colab compatibility (base image):
- categorized folder view built from relative symlinks mirroring the
README sections, rebuilt each boot; real .ipynb files never moved,
and the symlink tree is invisible to the sync state machine
- AMD-* notebooks shown only on an AMD/HIP host (autodetected)
- Docker-only strip of the Colab "Run all on Colab" intro sentence
from unedited notebooks (upstream notebooks unchanged)
- hoist %%capture above a leading #@title form so the cell runs
- the per-cell transformers-sidecar log is silent unless
UNSLOTH_ENABLE_LOGGING=1
Dependency pinning and naming: the curated notebook extras are pinned to
their resolved versions for reproducible rebuilds; decord is split into
its own fail-soft install (no aarch64 wheel). The lean base image is
renamed from :base to :core.
Adds tests/validate_studio_features.py, a static self-test for the
labextension plugins, overrides keys, and branding wiring.
