## Segmentation Toolbar & Stats

Workflow-specific toolbar with undo/reset/AI split buttons and segment
statistics. Used directly by mutation handlers for OOB swaps (via
`oob=True`) and by the combined step renderer for initial chrome
population.

------------------------------------------------------------------------

### render_toolbar

``` python

def render_toolbar(
    reset_url:str, # URL for reset action
    ai_split_url:str, # URL for NLTK split action
    undo_url:str, # URL for undo action
    can_undo:bool, # Whether undo is available
    extra_actions:tuple=(), # Additional elements for the right action group
    nltk_split_disabled:bool=False, # Whether NLTK Split button is disabled (current = NLTK pre-split)
    oob:bool=False, # Whether to render as OOB swap
)->Any: # Toolbar component

```

*Render the segmentation toolbar with action buttons.*

------------------------------------------------------------------------

### render_seg_stats

``` python

def render_seg_stats(
    segments:List, # Current segments
    oob:bool=False, # Whether to render as OOB swap
)->Any: # Statistics component

```

*Render segmentation statistics.*

------------------------------------------------------------------------

### render_seg_source_position

``` python

def render_seg_source_position(
    segments:List, # Current segments
    focused_index:int=0, # Currently focused segment index
    oob:bool=False, # Whether to render as OOB swap
)->Any: # Source position indicator (empty if single source)

```

*Render source position indicator for the focused segment.*

## Column Body Renderer

Renders the segmentation column content area with viewport and keyboard
infrastructure. Called by the combined step renderer (initial page load)
and the init handler (HTMX swap).

------------------------------------------------------------------------

### render_seg_column_body

``` python

def render_seg_column_body(
    segments:List, # Segments to display
    focused_index:int, # Currently focused segment index
    visible_count:int, # Number of visible cards in viewport
    card_width:int, # Card stack width in rem
    urls:SegmentationUrls, # URL bundle for all segmentation routes
    kb_system:Optional=None, # Rendered keyboard system (None when KB managed externally)
)->Any: # Div with id=COLUMN_CONTENT containing viewport + infrastructure

```

*Render the segmentation column content area with card stack viewport.*

## Shared Chrome Content

Functions that render segmentation-specific content for the shared
chrome containers. Used by the combined step renderer for initial page
load and by the init handler for OOB swaps.

------------------------------------------------------------------------

### render_seg_footer_content

``` python

def render_seg_footer_content(
    segments:List, # Current segments
    focused_index:int, # Currently focused segment index
)->Any: # Footer content with progress indicator, source position, and stats

```

*Render footer content with progress indicator, source position, and
segment statistics.*

------------------------------------------------------------------------

### render_seg_mini_stats_text

``` python

def render_seg_mini_stats_text(
    segments:List, # Current segments
)->str: # Compact stats string for column header badge

```

*Generate compact stats string for the segmentation column header
badge.*
