Reference segments can now apply a date offset just like baselines.
SQL template gains the {{date_offset}} token; both POST /reference and
PUT baseline/:logid pass it through. Existing sources need to
regenerate SQL to pick up the new template — old stored reference SQL
ignores the token (preserving prior verbatim behavior). The Baseline
form drops the "dates land verbatim" hint and shows the offset
control for both segment types.
Editing a segment now color-codes the source row amber with a ring
and tints the form border + header amber so the active connection is
visually obvious. Header label reads "Edit segment #3 — baseline —
note" instead of just "#43" (the internal log id).

Annotates each item with the design choice or open question. Notes
where existing spec coverage already addresses items 3 and 4
(structured filter groups and raw_where escape hatch) and where the
remaining work is wiring vs. greenfield.
