Location-Centric JobPosting Optimizer
=====================================

This script is a new version dedicated to optimizing JobPosting NDJSON
with a primary focus on geo-targeting and location-based SEO.

What's new:
1) Geo-Focused Title Generation
   - A completely new set of title templates that prioritize {city}, {state},
     and location-based urgency.
   - Titles are built to attract local candidates (e.g., "City Job: Role",
     "Hiring in City: Role").

2) Geo-Targeted Description Summary
   - The prepended SEO summary is now location-first.
   - New templates introduce the role, company, and salary all within
     the context of the specific {city}.

3) Geo-Contextual Enrichment
   - The AI enrichment layer now adds sentences specifically linking the
     role, company, and industry to the local area.

NEW IN THIS VERSION:
- Added a `--slightly-improve-title` flag. This provides a "light-touch"
  mode that ONLY appends geo-information (city, state, urgency) to the
  existing title and leaves ALL other fields (description, salary, etc.)
  in the record unmodified.
  (This mode is now more "intelligent", prioritizing new information
  and avoiding redundancy).

- NEW: Job Type Theming
  - The script now detects if a job is Full-Time, Part-Time, or Flexible.
  - It uses completely separate sets of templates (for both title and description)
    to theme the job posting around "careers" (for FT) or "flexibility" (for PT).

Usage
-----
Full Optimization:
python3 location_centric_schema_improver.py -i input.ndjson -o output.ndjson

Title-Tweak Only Mode:
python3 location_centric_schema_improver.py -i input.ndjson -o output.ndjson --slightly-improve-title

No Title Change (but full description/etc. optimization):
python3 location_centric_schema_improver.py -i input.ndjson -o output.ndjson --no-change-in-title
