Repurpose the Maximize2 button in SchematicViewer as a fullscreen
toggle (was reset-zoom; percentage label is now clickable for that).
Add matching fullscreen toggle to WaveformViewer alongside the scope
button. Both use a shared useFullscreen hook for Escape-to-exit and
body scroll lock. In fullscreen mode, the SVG canvas and plot areas
fill the viewport with proper dimension tracking via ResizeObserver.
- Cards (featured + gallery): hover adds -translate-y-1 + shadow-lg for
subtle lift-off-surface effect
- Homepage sections: replace hard border-b with gradient-fade dividers
that taper to transparent at edges
- Resistor button section: tighten vertical padding (py-10 → py-6)
- Notebook editor: cell spacing increased (space-y-0 → space-y-3),
add-cell button slides up on hover instead of abrupt opacity flash,
status bar gets more breathing room and lighter text
xDiv/yDiv were initialized as null and excluded from the main uPlot
effect's dependency array, causing the effect to bail on its null guard
and never re-run when the init effect set them to computed values.
Port 465/545A visual chrome from mcltspice docs into SpiceBook as a
toggleable waveform viewer skin. uPlot chart renders inside a CRT
screen with teal phosphor traces, graticule overlay, and scanlines.
Functional knobs control trace visibility (setSeries), X/Y zoom
(setScale) in standard 1-2-5 div steps. Digital readout bar shows
current trace, div values, and analysis type. Two switchable hardware
skins — 465 tan and 545A hammertone — persisted in localStorage.
New files: ScopeWaveformViewer.tsx, scope-skin.css
Modified: WaveformViewer.tsx (toggle), waveform-utils.ts (scope
palette, 1-2-5 sequence, stack-safe min/max), globals.css (scope vars)
SPICE cells now auto-trigger schematic generation when they mount
without an existing diagram, so the schematic leads the UI. Template
and empty cells are skipped.
Grid fallback layout replaced with wire-connected rendering: BFS-based
node tier classification places components vertically between supply
and ground rails, then routes wires by node type (power/ground bus
rails, L-shaped signal wires, star topology for 3+ connections).
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.
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.
