c9116c5d86 Add SEO meta tags, OG image generation, and astro-icon integration 
Wire astro-seo-meta for OG, Twitter Card, and canonical tags on all
pages. Add Satori + resvg dynamic OG image endpoints at /og/[id].png
with branded dark-theme cards. Replace inline SVGs with zero-JS
astro-icon rendering. SSR fetches use 5s AbortController timeout and
shared ID validation across all dynamic routes.

72eb073787 Clean URLs and waveform rendering fixes 
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.

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)
