- Working on vivo/OPPO marketing strategy projects
- Has deep knowledge of Apple design philosophy (wrote a detailed PDF about Jony Ive / Esslinger / Apple design history)
- Prefers professional, academic-style design writing
- Very particular about document structure — gets frustrated when structure is changed without permission
- Key rule: **never change document structure unless explicitly asked** — only upgrade content within existing structure

## Projects Completed Today

### 1. OPPO Find X9 Reddit Research & Copy Optimization
- Files: `OPPO_Find_X9_Report.md`, `OPPO_Find_X9_Full_Copy.md`, `OPPO_Find_X9_Insight_Report_Executive.md`
- Reddit user research → 5 user personas → 20+ real quotes → 5 insights → Apple-style copy for 8 modules (CN+EN) with spec sheets
- Executive report: 13 chapters with user voice → creative logic chain

### 2. Semrush Product Site Dwell Time Analysis
- Files in `semrush_report/` folder
- Compared vivo/OPPO/Honor domestic product sites using Semrush data
- Key finding: vivo.com.cn (independent .cn domain) has poor Semrush coverage vs oppo.com/cn and honor.com/cn (subdirectories of international domains)
- China-region weighted avg: Honor 1:17 > OPPO 1:13 > vivo 0:48
- Multiple PPT versions generated (v1-v4), final is `Semrush_停留时长_中国区_v4.pptx`

### 3. vivo Product Site Apple Quality Benchmark Guide
- Main file: `semrush_report/vivo产品站Apple品质对标指导手册.md`
- **v2.0 is the approved base structure** — 3 dimensions × 7 elements + 3 tech modules + 23-item checklist
- User's PDF about Apple design philosophy (Ive/Esslinger/Rams/Newson) was read and key insights extracted
- Content upgrades added to v2.0 structure (typography deep analysis from actual iPhone 17 Pro page data, consistency visual hammer concept, animation nature principles)
- Tech modules: A=Adaptive Loading, B=Progressive Enhancement/Degradation, C=Mobile Video Codec Optimization (Canvas bypass for Chinese browsers)
- HTML slides version: `semrush_report/apple_guidebook_slides.html` — Apple-style with Liquid Glass, scroll-snap, iOS 26 system colors
- Multiple PPT versions exist; HTML version is highest quality
- Was attempting to deploy to ZCMS (zeekr.zcms.com.cn) — login successful, navigated to apple_pdp site, but 28KB HTML too large for browser-based code editor paste

### Key Typography Finding (from live scraping iPhone 17 Pro page)
- Apple uses flattened font size hierarchy: 56→48→40→32→28→24→21→19→17→12px (ratio ~1.15:1)
- Priority expressed via **gray scale** (5 levels from #f5f5f7 to rgba(0,0,0,0.56)) rather than size contrast
- Almost all text uses Semibold 600 — "typographic flattening"
- SF Pro Display (>20px) auto-switches to SF Pro Text (<20px)
- H1 product name (34px) is intentionally smaller than Hero copy (56px)

## ZCMS Access
- URL: zeekr.zcms.com.cn
- Account: superadmin@zhinan.tech / 123456
- Target: sites → apple_pdp page
- Deployment was in progress when session hit compaction
