deep-technical-deep-dive
技術深潛。系統設計、實現細節、權衡與深度。
structure
The technical deep-dive archetype provides hands-on technical depth: design choices, implementation details, performance implications. It goes beyond narrative arc into the machinery itself.
- The problem statement — what system design challenge does this solve?
- Design dimensions (3–5 H2 sections) — each exploring one axis: latency vs throughput, consistency vs availability, space vs time, etc.
- Tradeoffs & conclusion — how do you choose given your constraints?
Works for: new database features, algorithmic innovations, infrastructure shifts, or architectural case studies.
required widgets
- Architecture diagram or flow chart — shows the components and their interaction
- Performance metrics or comparison chart — illustrates the tradeoffs being discussed
- Code snippet (optional but recommended) — worked example or pseudo-code

archetype-check rules
- ≥3 H2s (dimension headings, no fixed text — titles vary per post)
- `<p class="vg-deep-opener">` exists
- `<span class="vg-dropcap">` exists with exactly 1 character
- ≥2 inline `<svg>` elements (for architecture and metrics)
- Optional `<pre><code>` block for code examples
- `<p class="vg-deep-closer">` with `<strong>Take-away</strong>`
- Universal contract: opener, dropcap, closer with strong tag
when to use
Technical deep-dive shines when the story is about the mechanism itself: why this algorithm is superior, what tradeoff a new API makes, how a distributed system solved consistency. Not narrative-focused; systems-focused.
