Days before the first recorded day in history.daily were painted as a real
0.00/0 calls in the daily activity heatmap and the daily spend charts. That
zero is unknown, not measured, so those cells and bars now read "No data
recorded" instead of a currency zero. Genuinely idle days within recorded
history stay as real zeros.
- app: heatmap cells, the daily spend bars, and the daily-by-model columns
get a distinct no-data style plus a "No data recorded" hover for days before
the first recorded day.
- dash: the granular line chart drops buckets before the first recorded day so
no flat zero line is drawn before any history exists.
- data-start is derived in the UI layer from history.daily; payload shape is
unchanged.
Verified: app vitest 418 pass (7 new for the no-data behavior); app, dash, and
root typecheck clean; dash and app renderer vite builds succeed.
Every var(--t1/--t2/--t3/--hair/--hair2) and secondary legacy color
(--lav/--amber/--red/--mint/--blue/--purple/--cyan) repointed to the
canonical family (--ink/--mut/--mut2/--line/--line2, --warn/--bad/--ok,
--s-*); all legacy definitions and the plain.css alias shim deleted.
The explicit dark/light theme blocks carried drifted legacy literals
(including a pre-contrast-fix --t3), so this also extends the AA
contrast values to all four theme modes, which previously disagreed
with system-light.
grep-proven zero legacy usages. 235/235, build green.
- extract contiguousDailyWindow + formatChartDate to lib/period (shared)
- Spend "Daily spend by model": fixed contiguous 15-day window (zero-filled)
with an .ov-xax date axis, matching the Overview chart
- remove the horizontal gridlines from both charts (they read like data lines)
typecheck clean; 129/129 tests pass.
Drop the 11px stacked-segment cap so the bars fill their columns like the
Overview .chart; render only the last 15 days.
typecheck clean; 126/126 tests pass.
The StackedBars chart lived in a fixed 96px band, so when the grid
stretched its card to match the taller "By project" panel the bars
floated at the top over a large empty gap. Make the panel/body flex so
the chart fills the card height (min 120px) with bars bottom-anchored;
round stacked-segment corners only at the top/bottom of each column.
Table from getModels(): calls/input/output/cache-read/cost/saved with a model-family series
dot (reuses the ListRow helper). Unpriced/proxy rows show the dim "add alias" affordance +
dashes. By-model / By-task SegTabs re-fetch (byTask). Compare… is a visual affordance (M2).

Period-sliced StackedBars (history.daily[].topModels within the selected window via
a new shared lib/period.ts), the By-project list, and a Sankey rendered dynamically
from getSpendFlow (per-model hue ribbons). Lens tabs; series palette shared with the
legend. Adds a neutral .s-other class for the rollup segment.
