SchematicViewer now supports inline editing of component values
directly on the SVG. Clicking an editable value opens an overlay
input that updates the SPICE netlist on commit, triggering an
auto-redraw after 800ms debounce.
Added DOMPurify for SVG sanitization, netlist-utils for safe
value substitution in netlists, and wired schematic generation
through the notebook store with generation counters to discard
stale responses.
Parse netlists into component graphs and render circuit diagrams via
SchemDraw. Two layout strategies: loop layout for simple 2-terminal
circuits (RC, RL, voltage divider) and labeled grid for complex
circuits with active devices (BJT amplifiers, MOSFET).
Backend: netlist parser, schematic engine, POST API endpoint.
Frontend: SchematicViewer with zoom/download, stacked cell layout
showing schematic + SPICE editor + waveform simultaneously.
Vite inlines import.meta.env.PUBLIC_* at build time, not runtime.
Without this, the frontend falls back to localhost:8099 which doesn't
exist from the browser. Empty string means same-origin requests,
letting Caddy route /api/* to the backend.
Update frontend Dockerfile prod stage from Caddy static to Node.js
running Astro SSR server. Configure caddy-docker-proxy labels to
route /api/* to backend and everything else to frontend on the same
domain. Support empty PUBLIC_API_URL for same-origin API calls.
Switch from query-param routing (/notebook/?id=X) to Astro dynamic
routes (/notebook/rc-lowpass-filter). Add @astrojs/node adapter with
output: 'server' for on-demand route handling.
Fix formatEng/formatAxisValue crash on null values passed by uPlot
axis tick formatters. Add CORS origin for port 4322.
