docs: scripts v1.22.0 + website grid CHANGELOGs, ROADMAP R-38 shipped, R-45/R-46, REPORT

R-38 flips to SHIPPED with the live-canary evidence. Two new items registered
from tonight's work: R-45 (unified async-job feedback — five one-off progress
surfaces now exist and agree on nothing; the two lessons any framework must
encode are "probe the terminal state, never infer it" and "a source reporting
nothing is normal, not broken") and R-46 (verification copies are now visible
but still cannot be browsed and never expire — the invisible-result gap and the
disk-lifecycle gap, designed together because they are the same object).

Pre-invite checklist gains the golden note: build-golden v2.1.0 makes goldens
>= 0.147.x carry all four infra images; no rebuild for this alone.

REPORT-<topic>.md per the parallel-session rule — another session is writing in
this clone tonight, so the shared REPORT.md is left alone.

+## 2026-07-19 — Restored: the index grid background
+
+The subtle grid behind the hero was **not** removed on purpose. It lived as a fixed `body::before` in
+`index.html`'s inline `<style>` block and was dropped when `bed8675` ("D3 Part 2") migrated the page
+onto the shared `assets/site.css`; `dd54e4c`, the commit that created `site.css`, has no
+`body::before` at all. A porting omission, and nothing took its place. No asset was lost — it was
+pure CSS (two stacked `linear-gradient`s), so there was nothing missing from the worktree to notice.
+
+Restored, not redesigned: same 50px cells, same 1px lines, same 3% opacity, same `position:fixed` /
+`z-index:-1` so it does not scroll. One deliberate difference — the accent is the v2 `--blue`
+`#0083D8` instead of the retired legacy `#0088cc`, which `site_gates.py` bans. Scoped to
+`body.page-index`, because index is the only page that ever had it.
+
+`site.css` cache-bust bumped `?v=1` → `?v=2` on all seven pages (nginx caches 7 days). Verified live
+on desktop and in a 376px viewport: grid renders, no horizontal overflow, mobile layout unchanged.
