Per Justin: the native number-input spinners rendered as light boxes on
the dark theme, so they are gone app-wide (typing and arrow keys keep
working). Playback pacing: rounds now take 1000 ms at 1x, appearance
moments spread across 95% of the interval via a murmur3-style
full-avalanche hash, and each dot fades over 30% of the interval, so a
round reads as a continuous trickle instead of a flash.
The milestone 2 parity page becomes the spec's dashboard: app bar with
wordmark, disclaimer badge and About popover, theme toggle (persisted,
defaults to prefers-color-scheme, applied pre-mount to avoid a flash),
hero with the preset narrative and live toned percentages, scenario
toolbar, panel cards with skeleton loading and dim-while-refreshing,
legend, and footer. ComparisonTable evolves into the collapsed
ResultsTable (test moved along, plus a formatPct rounding case).
NetworkView renders the real topology with the spec's shape encodings.
The layout is seeded d3-force (mulberry32 random source, seeded initial
positions, 300 synchronous ticks, cached per graph hash); anisotropic
forceX/forceY pulls settle the cloud into the wide card shape so the
fit stays uniform-scale and the spacing organic. Justin asked for a
taller network area (380x230) and a reading caption under the legend;
the caption is study copy, so StudyPreset gains a readingCaption field.
Slices still to come keep their controls visibly parked: Export and the
panel kebab render disabled until slices 11 and 7.
App.vue fetches the default config, posts it to /api/comparison, and
renders ComparisonTable; the Vite dev server proxies /api to the Go
server so the browser sees one origin. src/lib/api.ts is the only
fetch code and uses exclusively generated types: no shape is defined
on the frontend. Scaffold example components removed.
Engine fix surfaced by the smoke test: a nil Go slice marshals to
JSON null, violating the generated 'educated: number[]' contract;
RunScenario now returns an empty slice instead.
Verified end to end: curl through the Vite proxy returns the golden
99/70/7. Vitest covers the table rendering; type-check, oxlint,
eslint clean. This completes the milestone 2 parity check.
Verbatim output of 'npm create vue@latest web -- --ts --vitest
--eslint --prettier' so this commit shows exactly what the official
scaffold generates; our own changes come separately. Lean per the
agreed choices: no Router/Pinia until a second page or shared state
exists. node_modules is ignored via the scaffold's own web/.gitignore.
