Adds SimulationEmbed component for embedding SpiceBook simulations in
book pages via iframe. Includes notebook creation scripts, op-amp fix
scripts, and cross-repo bugfix coordination thread.
- scripts/create-spicebook-notebooks.py: Creates 8 circuit notebooks
(555 timer, op-amp, comms, sensor) via SpiceBook REST API with full
SPICE netlists and educational markdown
- scripts/fix-opamp-notebooks.py: Patches 3 op-amp notebooks that fail
due to missing LM741.MOD by inlining a behavioral op-amp subcircuit
- docs/agent-threads/spicebook-embed-bugfixes/: 3-message coordination
thread documenting the 4 embed bugs (postMessage type, waveform CSS
vars, theme remount, light-mode overrides) and their verification
SimulationEmbed React island with click-to-activate iframes, theme sync
via postMessage/MutationObserver, and graceful fallback when SpiceBook
is unavailable. 12 simulations across 6 books (555 timer, op-amp,
semiconductor, formulas, communications, sensor). Books without
simulations render no extra markup. client:visible hydration defers
JS cost until scrolled into view.
- Integrate @astrojs/sitemap for automatic sitemap generation
- Add robots.txt with sitemap reference

Port hand-drawn visual effects (highlight, underline, circle variants)
with dark mode fixes: CSS variable-based text color, reduced highlighter
opacity in dark mode, and proper static text fallback for non-animated
instances. Applied orange underline to hero text, teal/green circles to
stats, yellow highlight to "Heritage", and underlines on collection headers.
