Adds docs/design-submission-page-2026-05-22.md (~600 lines) — a
dedicated submission-draft page at /projects/{id}/submissions/{code}/draft
with sidebar variable editor + read-only HTML preview + .docx export.
Reuses (resurrects from git) the deleted Slice 1 backend that t-paliad-230
ripped out — SubmissionVarsService (3677c81 + 1765d5e), in-house
SubmissionRenderer (8ea3509), TemplateRegistry (3677c81). All four
compile against today's services with zero API drift.
New schema: paliad.submission_drafts keyed on
(project_id, submission_code, user_id, name) with RLS via can_see_project.
Three slices: A = schema + page + variables-only export against universal
.docx; B = per-submission_code templates with fallback-chain registry;
C = toggleable passages.
Four material picks escalated to head in §11 (template authoring effort,
paliad.documents row, server-vs-client preview, inter-user draft
visibility). All other open questions defaulted to inventor (R)
recommendations from task brief.
No code. Read-only design phase per inventor → coder gate.
