ausboss 3f715a4af8 Ship the crush-list build-out: 7 new node files, replace button, video and LoRA polish

- New nodes: Image Resize plus the Utility group (Text, Integer, Float,
  Show Text, Math Expression, Select Every Nth, Split Batch, Merge
  Batches, Free Memory) - the dependency-free gaps that let shared
  workflows drop heavy packs.
- Replace with AusBoss nodes (prototype): preview-then-confirm graph
  rewrite swapping known third-party nodes for pack equivalents, with a
  tested translation map, per-node opt-out, and refuse-with-reason for
  nodes the pack cannot stand in for.
- Load Video: single-frame FRAME picker, an honest "what will load"
  label from the probed source rate, drop-a-video-to-restore. Save
  Video: format-aware widgets and a file_path output. Stitch Inpaint
  gained a blend_mask output, Select Frame negative from-the-end
  indexing, Image Size a batch count - all appended, saved workflows
  load unchanged.
- LoRA Loader: drag-to-reorder rows, hover thumbnails on rows, file
  size and date in the info card.
- Appearance: flagship scheme deepened to slate-teal; the retired
  bright-teal pair upgrades automatically via LEGACY_SCHEME_PAIRS.
  Optional queue-completion chime, off by default.
- Image Resize invariant: pixels are only invented on an explicit
  width+height pad request - scale-derived modes resolve divisible_by
  snaps with a sub-half-step resize, never bars.
- Docs refreshed for six stale pages, stale text and metadata fixed
  across the pack, the panel-height rule codified in AGENTS.md and the
  brand skill, and ausboss_node_tour.json added - a model-free example
  exercising 17 node types in one graph.

Validated: scripts/validate_nodes.py (24 files), 300 JS tests, all
Python suites under the ComfyUI embedded interpreter.

Load Video

Loads a video from ComfyUI's input folder as an IMAGE frame batch plus its audio. One responsive player shows the source and previews the selected trim. Drag the high-contrast IN and OUT handles below it, drag the selected range to move the whole window, or type exact seconds into the two fields. The playhead follows each edit, so the frame at either boundary is visible while trimming.

Playback is constrained to the selected window. LOOP repeats it; turn loop off and playback pauses at OUT. The reload button refreshes the source without creating a second preview. Tall videos use object-fit: contain, and the player height follows the node width with a compact lower bound.

FRAME switches the loader into a frame picker: the trim strip becomes a single scrub rail, and only the frame at the marker loads — a one-image batch, ready for image workflows without a separate frame-select node. Click or drag anywhere on the rail to choose the frame, or type an exact time into the AT field. Playback runs the whole source freely in this mode so you can hunt for the right moment; the trim window returns untouched when you toggle back.

The label between IN and OUT reports what one Run will actually load — e.g. 0:04.0 of 0:10.0 · 48 frames @ 12 fps, or 1 frame at 0:05.2 while FRAME is on. The preview cannot re-render every_nth frame drops or a max_frames cap, so it counts them instead: the frame total and playback rate come from the source's real frame rate (probed from the file, since the browser's player never exposes it) with every_nth and max_frames applied. When a deciding value arrives over a link, or the rate cannot be probed, the count drops out rather than guessing.

Drop a video onto the node

Dropping a video file onto this node makes it the node's source: the file is copied into ComfyUI's input folder (re-dropping identical content reuses the existing copy) and selected, while the rest of your canvas stays put. If the file is an AusBoss save, the workflow embedded in it is read too, and the trim, every_nth, max_frames, sizing and FRAME values its Load Video node stored are restored onto this one — the clip reopens the way it was loaded before. The same file dropped on empty canvas keeps its old meaning: the embedded workflow replaces the whole graph.

Controls

video: A file in the input folder; the upload button adds new ones.
IN / start_seconds: Skip everything before this time.
OUT / end_seconds: Stop at this time; 0 means the source end until a handle is moved.
every_nth: Keep one frame in this many — 2 halves the frame count. The fps output divides to match, so the clip still plays at real speed downstream.
max_frames: Stop after this many kept frames; 0 loads the whole trim window. Caps memory on long clips — the decode ends early instead of loading and discarding.
LOOP: Repeat the selected window during preview.
FRAME / single_frame: Load only the frame at the IN time as a one-image batch; end_seconds, every_nth, and max_frames are ignored while it is on.
↻: Reload the selected source preview.
custom_width / custom_height: 0 keeps the source size. Set one side only and the other follows the aspect ratio, rounded to an even number.

Outputs

frames: Trimmed BHWC frame batch.
audio: The same trim window; a silent track when the file has no audio.
frame_count / fps / width / height / duration: Ready-made wiring for video combine nodes and info displays. fps is the source rate divided by every_nth; duration covers the returned frames, not the whole file.
video: A lazy core VIDEO handle for the same source trim at its native size. Connect it directly to core video-aware nodes without materializing a second frame batch. every_nth does not apply to it — the VIDEO wire carries the source as-is — though a max_frames cap shortens its window to match the kept frames. Older ComfyUI cores without the VIDEO API return no handle; the original seven outputs remain unchanged.

The trim window is decoded directly — untrimmed parts of the video are never loaded into the frames output, while the video output stays lazy until a downstream consumer requests it.

While it runs

Decoding happens off ComfyUI's execution thread, so the server keeps answering while a long trim loads. The node fills its progress bar frame by frame whenever the source declares a frame count, and Cancel stops the decode within a frame instead of at the end of the file.
