Proper noun detection (flagging capitalized phrases like "Getting
Started", "Generate Design", "Introduction Getting Started") now
disabled by default. Enable via popup → Options tab → Detect proper
nouns.
The pattern-based detection (IPs, emails, API keys, addresses, paths,
etc.) remains always-on and reliable. The capitalized phrase heuristic
was producing too many false positives on normal UI phrases, headings,
and instructions — adding words to the filter was a losing game.
Added detectProperNouns toggle to popup Options tab.
Updated README to note it's opt-in.

Massively expanded the common words filter — added ~500 common verbs,
nouns, and adjectives that frequently appear capitalized in titles,
headings, UI buttons, and instructions. 'Generate Design', 'Create
Account', 'Search Filter', etc. are no longer flagged as PPI.
Updated both content.js and auto-detect.js with the same word list.

Proper noun heuristic:
- Changed from matching any single capitalized word to requiring
TWO OR MORE consecutive capitalized words (e.g. "Acme Corp")
- Single capitalized words at sentence starts were causing massive
false positives — every sentence starts with a capital letter
- Minimum 5 characters total and 2 proper words required
Ignore button:
- Each PPI warning item now has an X (ignore) button alongside
the + (add mapping) button
- Ignored values are persisted to storage (ss_ignored_ppi) so
they stay dismissed across page reloads
- Ignored values are skipped in both pattern detection and
proper noun detection
- Clicking ignore removes the item from the warning and re-scans

Import parser:
- Passwords now imported from Chrome/Firefox/Bitwarden/1Password CSVs
as exact-match auto-redacted mappings (→ [REDACTED-PASSWORD-N])
- Catches passwords in any context, not just key=value patterns
Proper noun heuristic:
- Auto-detect scanner now catches capitalized words mid-sentence as
potential names, company names, or project names
- Filters against 200+ common English words, programming terms, days,
months to reduce false positives
- Added to both content.js (page world) and auto-detect.js (popup)
README:
- Documented proper noun detection with examples
- Documented bulk import with all supported formats
- Added Sync features section (auto sync, conflict resolution,
version history, connected devices)
- Added Organization/Team section with policy format
- Added tamper protection documentation
- Added Legal section with liability analysis
- Updated architecture with all new modules

Scans outbound messages AFTER all substitutions for personal data
the user forgot to configure:
- Private/public IP addresses (skips 127.0.0.1, 8.8.8.8, etc.)
- MAC addresses
- Street addresses ("123 Main St")
- GPS coordinates
- Dates (possible DOBs)
- EIN/tax IDs
- Home directory paths not caught by smart patterns
- Shell prompts (user@host)
- Git remotes (reveals username/org)
- Environment variable assignments (HOME=, USER=, etc.)
Shows a floating dark warning banner (top-right, auto-dismisses
after 15s) listing each detected item with its type, value, and
hint. Skips values already in the user's identity config.
Also shows PPI warnings in the popup Test tab and adds toggle
in Options to disable auto-detect.
