DESIGN / HANDOFF SNAPSHOT — 2026-03-12 v06

Current beta: index_beta_2026-03-12-v06.html
Current canonical docs: canonical-docs-2026-03-12-v06

Delta-bundle rule:
- ZIP lives inside the date directory.
- ZIP root contains only changed root files for the iteration.
- ZIP does not contain the date directory itself.
- Root should normally include the current beta, handoff.txt, and current progress log.
- Canonical docs live in canonical-docs-YYYY-MM-DD-vNN/.

Current implementation targets:
1. QR geometry correct on first paint.
2. Everything visible should render immediately on load.
3. Remaining out-of-view feeds may append after first useful paint.
4. URL art should fit the full URL when reasonably possible.
5. URL-art export should be as WYSIWYG as practical.

Documentation routing map:
- requirements_en.html = user-visible requirements and non-regression rules
- architecture_en.html = structural rendering/state rules
- system_en.html = active runtime issues and operations
- developer_en.html = workflow, packaging, handoff, and documentation governance
- index_en.html = documentation overview and ownership map
- manuscript_en.html = personal / non-spec authored material

Carry-forward rule:
Explicit prior prompt requirements remain binding until deprecated. The user should not have to restate them.
