jaredandClaude Sonnet 5 fa35d97269 Clean up the hero chart: remove watermark, fix label collisions, round axis ticks
Deploy to git-pages / deploy (push) Successful in 12s
The district-name watermark inside the arrests-over-time chart was
redundant with the page's own heading and was the direct cause of a label
collision (a high point's rate label rendered on top of it). Removes it.

Two more collisions, both edge cases the screenshot happened to hit: the
first wave's label sat close enough to the plot's top that it could
overlap the topmost gridline text, and a point sitting flush on the plot's
left edge had its center-anchored label bleed into the y-axis tick labels.
Fixes both with more vertical clearance and edge-aware text anchoring
(first point anchors right, last point anchors left, matching the same
fix already applied to chart 4's wave ticks before that chart was cut).

Adds a shared niceTicks() utility (Heckbert's nice-numbers algorithm) so
axis ticks read as round numbers (0/100/200) instead of arbitrary
fractions of the data max (0/113/226/339) — applied to all three charts
for consistency. Also fixes a legend/mark mismatch in the arrests-over-time
chart (the modeled series legend showed a diamond; the actual mark is a
dot) by adding a proper 'dot' shape to ChartLegend.

jaredandClaude Sonnet 5 67caa02fe2 Redesign chart visualizations to match Civilytics white-paper style
Deploy to git-pages / deploy (push) Successful in 18s
Rebuilds all 6 charts around a validated categorical race palette, row-based
sex encoding, and a consistent observed-vs-modeled mark convention (diamond
vs. filled bar/density) instead of ad hoc per-chart color schemes. Adds a
shared student-group filter (defaults to all 8 groups) that scopes every
chart's data from one place in ChartPanel.

Drops the D3 dependency entirely in favor of plain SVG, removing the
imperative-DOM bug class behind this app's repeated "fix the fix" commits.
Replaces the fake symmetric-normal posterior approximation with a skewed,
median-preserving fit to the API's interval bounds, clearly labeled as an
approximation. Fixes two broken SVG fill attributes, a decorative model
dropdown that never affected its chart, dead code, an orphaned component,
and a broken CSS token reference.
