Ryan Malloy	2ddc08cd3a	Add schematic thumbnails, descriptions to notebook cards and resistor color guide ... Notebook cards now show schematic SVG thumbnails (on Mims green background) and description snippets extracted from the first markdown cell. The backend extracts both from already-loaded notebook data at zero additional I/O cost. New ResistorColorGuide section between the pipeline strip and featured notebooks explains the 4-band color code with an annotated zigzag diagram and reference table using the same BAND_HEX colors from the schematic renderer. Also switches docker-compose.dev.yml from direct port mapping to Caddy labels, matching the production routing pattern and avoiding port conflicts.	2026-02-21 08:56:48 -07:00
Ryan Malloy	8abd7719bf	Initial SpiceBook MVP: notebook interface for circuit simulation ... Phase 1 implementation with ngspice backend and Astro/React frontend: Backend (FastAPI): - ngspice subprocess engine with custom .raw file parser - Notebook CRUD with .spicebook JSON format (filesystem storage) - Simulation endpoints (standalone + cell-in-notebook) - SVG waveform export endpoint - 18 REST API routes, 5 passing tests Frontend (Astro 5 + React 19): - Notebook editor as React island with Zustand state management - CodeMirror 6 with custom SPICE language mode (syntax highlighting for dot commands, components, engineering notation, comments) - uPlot waveform viewer with transient and AC/Bode plot modes - Markdown cells with edit/preview toggle - Notebook list with card grid UI - Dark theme, Tailwind CSS 4, Lucide icons Infrastructure: - Docker Compose with dev/prod targets - Caddy-based frontend prod serving - 3 example notebooks (RC filter, voltage divider, CE amplifier)	2026-02-13 01:44:38 -07:00
