_filter_footer_words now returns page number info (text, y_pct, number)
instead of just removing footer words. The page number is included in
the grid result as `page_number` and displayed in the frontend summary
bar as "S. 233".
This preserves page numbers for later page concatenation in the
customer frontend while still removing them from the grid content.

Hybrid approach mirroring English IPA:
- Primary: wiki-pronunciation-dict (636k entries, CC-BY-SA, Wiktionary)
- Fallback: epitran rule-based G2P (MIT license)
IPA modes now use language-appropriate dictionaries:
- auto/en: English IPA (Britfone + eng_to_ipa)
- de: German IPA (wiki-pronunciation-dict + epitran)
- all: EN column gets English IPA, other columns get German IPA
- none: disabled
Frontend shows CC-BY-SA attribution when German IPA is active.

Our IPA system only has English dictionaries (Britfone MIT, eng_to_ipa
MIT). The "IPA: nur DE" option was useless at best and misleading.
Removed from dropdown, type definition, and API validation.
Syllable DE mode stays — pyphen has a German hyphenation dictionary.

The dropdowns only updated state but didn't trigger buildGrid().
Now a useEffect watches ipaMode/syllableMode and rebuilds
automatically (skipping the initial mount).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Extend ipa_mode and syllable_mode toggles with language options:
- auto: smart detection (default)
- en: only English headword column
- de: only German definition columns
- all: all content columns
- none: skip entirely
Also improve English column auto-detection: use garbled IPA patterns
(apostrophes, colons) in addition to bracket patterns. This correctly
identifies English dictionary pages where OCR produces garbled ASCII
instead of bracket IPA.

Backend: Remove en_col_type fallback heuristic (longest avg text) that
incorrectly identified German columns as English. IPA now only applied
when OCR bracket patterns are actually found. Add ipa_mode (auto/all/none)
and syllable_mode (auto/all/none) query params to build-grid API.
Frontend: Add IPA and Silben dropdown selects to GridToolbar. Modes
are passed as query params on rebuild. Auto = current smart detection,
All = force for all words, Aus = skip entirely.

Users can now right-click any cell to set text color (red, green, blue,
orange, purple, black) or remove the color bar without changing text.
A "reset" option restores the OCR-detected color. This enables accurate
Ground Truth marking when OCR assigns colors to wrong cells.

- Color bar (red/colored indicator) now only shows when word_boxes
text still matches the cell text — editing the cell hides stale colors
- New "Auto-Korrektur" button: detects dominant prefix+number patterns
per column (e.g. p.70, p.71) and completes partial entries (.65 → p.65)
— requires 3+ matching entries before correcting

Resize handle: wider (9px), z-40 (above z-30 buttons).
Add-column button moved to bottom-right corner to avoid overlap.

- New ImageLayoutEditor: SVG overlay on original scan with draggable
column dividers, horizontal guidelines (margins/header/footer),
double-click to add columns, x-button to delete
- GridTable: MIN_COL_WIDTH 40→80px for better readability
- Arrow up/down keys navigate between rows in the grid editor
- Ctrl+Click for multi-cell selection, Ctrl+B to toggle bold on selection
- getAdjacentCell works for cells that don't exist yet (new rows/cols)
- deleteColumn now merges x-boundaries correctly
- Session restore fix: grid_editor_result/structure_result in session GET
- Footer row 3-state cycle, auto-create cells for empty footer rows
- Grid save/build/GT-mark now advance current_step=11

- New document category "Woerterbuch" (frontend type + backend validation)
- Column delete: hover column header → red "x" button (with confirmation)
- Column add: hover column header → "+" button inserts after that column
- Both operations support undo/redo, update cell IDs and summary
- Available in both GridEditor and StepGridReview (Kombi last step)

Changed `typeof grid.zones[][]` to `GridZone[][]` which was causing
a silent build error, preventing the vsplit zone grouping logic from
being compiled into the production bundle.

Pages with two side-by-side vocabulary columns separated by a vertical
black line are now split into independent sub-zones before row/column
detection. Each sub-zone gets its own rows, preventing misalignment from
different heading rhythms.
- _detect_vertical_dividers(): finds pipe word_boxes at consistent x
positions spanning >50% of zone height
- _split_zone_at_vertical_dividers(): creates left/right PageZone objects
with layout_hint and vsplit_group metadata
- Column union skips vsplit zones (independent column sets)
- Frontend renders vsplit zones side by side via flex layout
- PageZone gets layout_hint + vsplit_group fields

Post-processing steps like 5h (slash-IPA conversion) modify cell.text
but not individual word_boxes. The colored per-word display showed
stale word_box text instead of the corrected cell text. Now falls
back to the plain input when texts don't match.

Footer rows (e.g. page numbers) now show "F" in amber below the row
number, mirroring the blue "H" label for headers.

When union columns from multiple content zones are applied, column
boundaries can span wider than any single zone's bbox. Using
zone.bbox_px.w as the scale reference caused the total scaled width
to exceed the container, pushing the table off-screen.
Now uses the actual total column width sum as the scale reference,
guaranteeing columns always fit within the container.

Backend: add layout_metrics (avg_row_height_px, font_size_suggestion_px)
to build-grid response for faithful grid reconstruction.
Frontend: rewrite GridTable from HTML <table> to CSS Grid layout.
Column widths are now proportional to the OCR-measured x_min/x_max
positions. Row heights use the average content row height from the
scan. Column and row resize via drag handles (Excel-like).
Font: add Noto Sans (supports IPA characters) via next/font/google.

When a cell has colored words (red !, blue phonetics), render each
word as a separate span with its own color instead of coloring the
entire input text with the first non-black color found.
Switches to editable input on cell selection (click).

- Add color/color_name/recovered fields to OcrWordBox type
- GridTable: show colored text + left-edge color indicator strip
- GridEditor: show color stats and recovered count in summary bar

Backend: new grid_editor_api.py with build-grid endpoint that detects
bordered boxes, splits page into zones, clusters columns/rows per zone
from Kombi word positions. New DB column grid_editor_result JSONB.
Frontend: GridEditor component with editable HTML tables per zone,
column bold toggle, header row toggle, undo/redo, keyboard navigation
(Tab/Enter/Arrow), image overlay verification, and save/load.
