docs: ratify Q1-Q12 — submission generator v2 design final (m/paliad#141)

All 12 §11 design questions ratified by m on 2026-05-26 via
AskUserQuestion (paliadin-authorised override per instruction msg #2391).

Picks matching inventor recommendations (9 of 12):
 Q1 separate submission_sections table
 Q3 Gitea-backed body + thin DB row
 Q4 contentEditable + Markdown + in-house serializer
 Q5 section anchors + in-house MD->OOXML walker
 Q7 split content_md_de + content_md_en from day 1
 Q8 Go map for per-submission_code section defaults
 Q9 4 visibility tiers (private/team/firm/global)
 Q11 collapsed preview pane by default
 Q12 moot (superseded by Q2 simplification)

Deviations from recommendation (3 of 12):
 Q2 SIMPLIFY further — m: "sounds overengineered". Building blocks
    become plain text paste sources. No building_block_id column on
    sections, no _versions table referenced from sections, no
    refresh-from-library affordance. Slice G dropped.
 Q6 Auto-upgrade all 11 existing drafts at mig-148 apply time (not
    opt-in per draft). v1 fallback render path stays compiled in.
 Q10 *_auto kind removed. Caption/letterhead/signature sections are
    regular prose rows seeded with bag-driven Markdown; lawyer can
    edit/hide. Untouched drafts export identically to v1.

Body sections updated inline (§4.3 schema, §4.4 BB tables, §6.3
seeding, §8.3+8.4 BB insert, slice plan A/C/G, §11 ratification notes,
§14 risks #8+11, §17+18 acceptance + gate). §11 retains the historical
recommendation matrix.

Status: ALL DESIGN QUESTIONS RATIFIED — design doc final, ready for
Slice A coder shift. Inventor parks per hard gate. Head decides hire.
