Subject: [PATCH 1/6] Extract inline CSS styles to stylesheet classes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit removes inline style attributes from HTML templates and Python
renderer code, extracting them into appropriate CSS files for better
maintainability and consistency.

Changes:
- transcript.html: Removed inline styles from session-subtitle
- index.html: Removed inline styles from summary-stats-flex and transcript-link-hint
- session_nav.html: Removed inline styles from nav-hint and session-preview
- renderer.py: Replaced inline image styles with CSS classes (tool-result-image, uploaded-image)
- message_styles.css: Added session-subtitle and image styling classes
- global_styles.css: Added summary-stats-flex class
- project_card_styles.css: Added transcript-link-hint class
- session_nav_styles.css: Added nav-hint and session-preview classes

Skipped dynamic styles:
- timeline.html JavaScript styles (runtime-manipulated)
- ANSI color conversion in renderer.py (runtime-computed values)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

- #ff9800 → var(--user-color)
- #9c27b0 → var(--assistant-color)
- #4caf50 → var(--tool-use-color)
- #f8f9fa → var(--bg-neutral)
- #ffffff66 → var(--white-dimmed)
- #9c27b066 → var(--assistant-dimmed)
- #2196f3 → var(--system-warning-color)

Files modified:
- filter_styles.css: 11 color replacements
- message_styles.css: 9 color replacements
- project_card_styles.css: 7 color replacements
- search_styles.css: 25 color replacements
- session_nav_styles.css: 9 color replacements

Subject: [PATCH 3/6] Fix session_subtitle template access error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The template incorrectly accessed message.session_subtitle.session_id
even though session_subtitle is a string. Changed to use message.session_id
directly to avoid AttributeError.

Subject: [PATCH 5/6] Add missing CSS variable definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add --text-primary and --bg-neutral to :root variables.
Fix filter-toolbar to use --neutral-dimmed (with alpha) instead of
--bg-neutral (solid) to match the original #f8f9fa66 value.
