- Headings: System default (GitHub 의 default
-apple-system, BlinkMacSystemFont, Segoe UI, ...) - Body: 동일 (GitHub-native 정합)
- Code:
ui-monospace, SFMono-Regular, Consolas, ...(GitHub 의 default monospace)
별도 webfont 사용 안 함 (GitHub README rendering 정합).
Audience: Kubernetes platform engineers / DBAs / SRE.
Voice principles:
- Direct — bullet-point over paragraph where possible
- Evidence-based — claims include benchmark / SLA / link
- Vendor-neutral — reference upstream PostgreSQL but do not embed/wrap third-party operators
- License-aware — MIT/BSD/Apache-2.0/PG-license dependencies only
Avoid:
- Marketing superlatives ("blazing fast", "revolutionary", "best-in-class")
- Vague comparisons ("X-class quality") — qualify with specific metric or benchmark
- Time-based deadlines in roadmap (use
standards/roadmap.md §1.1— feature checklist instead)
