report used Georgia (serif) for body prose, which looked dated/out of place
(it's the default for markdown and html_fragment, so most text artifacts).
Switched it to the system sans stack and pinned that same stack explicitly
in tasks too, so all three document themes (base/report/tasks) share one
font family rather than matching only by inheritance. Headings, table
cells (monospace), and table headers (Arial) are unchanged.

Table cell data (td) now uses a fixed-width stack (Consolas, SF Mono, Menlo,
...) at 0.92em so columns — especially numbers — align and scan cleanly;
headers (th) use Arial/sans for clear contrast against the mono data.
Applies to markdown and html_fragment tables via the shared base.css.

markdown/html_fragment (report, tasks, base themes) and the json/csv viewers
each used their own near-white background (cream #fffaf0, light-blue
#f7fbff, or plain white). They now all use #faf9f6 — the same off-white the
preview area uses for image/binary artifacts — so browsing across kinds is
visually consistent.
Left as-is on purpose: deck (intentional dark slide background; switching it
would require reworking its light text colors), html_full (served verbatim,
poster owns styling), and pdf (the browser's own viewer chrome). Existing
json/csv artifacts keep their baked-in #fffaf0, which is visually
indistinguishable from #faf9f6; only new ones get the exact value.

Markdown pipe-tables and hand-written html_fragment <table> markup already
rendered - the only existing rule was 'max-width: 100%', so they came out
as bare, unbordered browser-default tables. Adds borders, header
background, cell padding, and zebra striping, plus a display:block +
overflow-x:auto pattern so wide tables scroll horizontally instead of
squeezing columns or breaking page layout.
Lives in base.css, which report.css and tasks.css both @import, so it
applies to every existing and future markdown/html_fragment artifact
immediately - no agent-side change needed, since this is rendered live
from CSS rather than baked into stored HTML.

Enables codehilite on the markdown renderer (Pygments, 'friendly' style,
vendored as static/themes/pygments.css) so fenced code blocks get real
syntax highlighting with zero client-side JS - matching the "themes are
CSS-only" stance in framework_artifact_rendering.md. Verified live against
the running dev instance: a fenced python block renders with highlighted
keyword/string/function spans.
This was Gap 2 from planning/2026-09-02-artifact_kind_gaps_for_frequent_agent_output.md,
picked as the first fix since it needed no new kind or design decision -
just enabling an existing markdown extension.

Daybook: a self-hosted, multi-user Django + DRF app where agents, scripts,
or people publish artifacts and each logged-in user browses their own
time-ordered, label-filterable feed.
This squashes prior local development history (kept privately on a separate
branch) into a single clean starting point for the public repository.
