Add find_redaction_in_region() that searches for a black rectangle
within a specific page region identified by the LLM. Uses a lower
minimum area threshold (100px vs 500px) since the LLM provides
spatial guidance, preventing merged redactions and false positives.

Introduce llm_detect.py that sends OCR lines to Claude Haiku to identify
redaction locations via broken text patterns (garbled chars, brackets,
pipes). The LLM returns boundary words which are mapped back to pixel
positions using OCR character data. Includes comprehensive tests covering
single/multiple redactions, line start/end edge cases, and error handling.

Instead of using a neighboring line (which may have a different font/size,
e.g. email header vs body text), crop the non-redacted left or right
portion of the actual redacted line for font detection. Falls back to
clean neighbor lines only when neither side has enough text (>=50px).

Replace OCR-based offset calculation with pixel alignment that slides
rendered text across the page image to find the exact position with
maximum Dice overlap. Also fix char filtering to use center-point
(c.x + c.w/2) instead of right-edge, recovering characters like "nt"
in "Sent" that partially overlap the redaction box.

Redaction boxes corrupt OCR text and add spurious dark pixels that
break pixel-based font scoring. Now uses wider crop padding (3x)
and prefers the nearest non-overlapping line for font detection.

Replace word-width MAE scoring with pixel-overlap Dice scoring in both
_full_search() and _fine_search(). Both functions now accept a line_crop
parameter and use _score_font_line_pixel() instead of _score_font_line().
Comparisons are flipped (higher is better). The size range is now derived
from the OCR line height instead of the fixed SIZE_RANGE constant, and
uses step=1 since pixel scoring has sharp peaks at the exact font size.

Add _score_font_line_pixel() which renders candidate text and compares
pixels against the actual page image using Dice coefficient overlap.
This captures glyph shape differences that the old word-width MAE
approach cannot distinguish (e.g. serif vs sans-serif).

Centralize 21 repeated color values into :root variables.
Makes theme changes trivial and improves readability.

Reorganize the monolithic 1,436-line frontend into 9 focused modules:
types, state, dom, canvas, viewport, associates, popover, solver, main.
No build step — browsers load ES modules natively. JSDoc @typedef
annotations provide type safety via @ts-check + jsconfig.json.

Without flex properties, #viewer-section collapsed to content
height (just the controls bar), giving the workspace 0 height
and causing zoom to compute as 0%.

- Remove unused detect_redactions import from app.py
- Add de-duplication check in dblclick handler to prevent
creating duplicate redaction entries for the same dark region

Shift+drag now adjusts gap width (was ctrl+shift+drag).
Manual redaction marking via shift+drag is removed;
users now double-click to spot-detect redactions.

Extract inline analysis logic from the analyze endpoint into a reusable
_run_analysis() helper function, then add a new /api/redaction/spot
endpoint that chains spot_redaction detection with analysis in one call.

Uses OpenCV connected components to find a dark region at a specific
click point, complementing the existing detect_redactions() which
auto-detects all redaction bars via morphological operations.

Adds green segment overlay, floating font toolbar, bottom text edit
bar, and backend offset guess to the redaction-centric UI.

Hold Shift and drag on the canvas to draw a custom redaction
rectangle. Creates an unanalyzed redaction entry that triggers
on-demand OCR when clicked.

Replace line list with redaction list, add canvas-native redaction
overlays with hit-testing, popover with on-demand analysis and
solver integration. Remove old font/segment/overlay controls.

When a user clicks a redaction, this endpoint crops the surrounding line,
runs Tesseract OCR, detects the font, and returns text segments (before/after
the redaction), gap width, font info, and character-level bounding boxes.

Replace upfront OCR + font detection + overlay rendering with lightweight
OpenCV-based redaction detection. Upload now just rasterizes and detects
black rectangles, making it significantly faster. Remove the overlay
endpoint and update the data endpoint to return redaction bboxes.

Shift from upfront OCR to redaction-centric workflow with OpenCV
detection, canvas-native clickable overlays, on-demand analysis,
and per-redaction popover solver UI.

Fetches from 3 data sources (HuggingFace parquet, rhowardstone entities,
Epstein Exposed API) plus 8 court-verified addresses. Merges, deduplicates,
validates, and writes 644 unique emails to unredact/data/emails.txt.

Victim names are stored as a flat set of lowercased name variants
with no person details — the V badge appears but is not clickable,
protecting victim identities. A result can show both T1/T2/T3 and V
badges simultaneously.
- 15 known victims from public court records → 43 name variants
- Enabler/perpetrator categories promoted to T2
- Purple V badge with pointer-events disabled
- Victim matching uses prefix/suffix combination like associate matching
