Subject: [PATCH 04/27] style(car): unify photo detail modal visual style with
 profile modal

- Replaced solid dark background of `.modal-overlay` with `--overlay-backdrop` and matching blur to match other modals.
- Updated `.detail-modal` to use glassmorphism variables (`--glass-bg-heavy`, `--glass-blur`, `--glass-shadow`, etc.) for consistency with the profile modal.
- Adjusted `modal-zoom` transition to target only `.detail-modal` for scaling instead of the entire overlay wrapper.

Subject: [PATCH 06/27] fix(car): decouple pearl shell trigger zone from photo
 wall

- Created a dedicated `.pearl-shell-trigger-zone` matching the exact position and size of the PearlShell component.
- Removed click handler from the entire `.photo-wall` to prevent misclicks.
- Added `position: relative` and higher `z-index` to `.photo-grid` to ensure photos remain clickable over the trigger zone.
- Used `.stop` modifier on photo click events to prevent event bubbling.

Subject: [PATCH 24/27] feat: share photos and AI memories between bound
 partners
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bound mom/dad users now see each other's photos and AI memory facts.
Photos are queried by family IDs (user + partner), with a combined
limit of 50. AI chat memories load both partners' facts with source
labels ([她]/[他]/[家庭]) and new facts record OwnerUserID for
attribution. The frontend shows owner badges when multiple owners
are detected.

Subject: [PATCH 26/27] fix: trigger memory update toast for fact saves and
 corrections
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The memory_updated flag previously only tracked legacy profile updates.
Now it also fires when structured facts are saved or corrected, so the
frontend "记住了" toast appears reliably.

Subject: [PATCH 27/27] fix: dedup memory facts per-user instead of per-family
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When bound partners both state the same fact (e.g. "我喜欢吃苹果"),
each should have it recorded independently. Changed dedup check from
family-scoped FactExistsByContentFamily to per-user FactExistsByContent.
