Why: the default skin was too warm/neutral and the pyramid + venn never quite read the way they should. Also prepping for public sharing, so the example diagrams needed to drop the littlemight-specific copy. Changes: - New five-color palette: jet-black ink, atomic-tangerine accent, white-smoke paper, blue-slate muted, silver hairlines. Replaces warm-stone + rust across every variant + dark-mode tokens. - Default background is clean paper; dot grid + framed container are now opt-in variants (uncomment in template to enable). - New consultant-special quadrant variant (example-quadrant-consultant.html) — 2×2 scenario matrix with named cells, double-ended axes, one focal quadrant; house skin, not a separate visual language. - Pyramid redrawn as a true triangular silhouette with shared edges on one slope (stacked polygons on a single triangle outline, no kinks). - Venn redesigned: dark-fill triple-intersection with white text, circle labels moved inside non-overlap lobes, pair-overlap labels removed, legend dropped. - Example content genericized (content site / product timeline / content platform instead of littlemight-branded copy). - Screenshots regenerated at 2× DPI; added quadrant-consultant.png (14th diagram in the gallery). - README: hero-first opener, preserved Why-I-built-it section, UTM tags on littlemight + bestself links, palette description updated.

Sequence
Best for: request/response flows, protocol exchanges, multi-actor interactions over time, API call traces, incident reconstructions.
Layout conventions
- Actors as boxes in a horizontal row at the top.
- Lifelines: dashed vertical lines descending from each actor to the bottom.
- Messages: horizontal arrows between lifelines; time flows top→down.
- Activation bar: narrow rectangle (
w=8, muted fill, 0.8 hairline stroke) on a lifeline spanning the interval that actor holds control. Stack for nested calls. - Self-messages: short U-shaped loop returning to the same lifeline; label right of the loop.
- Return messages: dashed line in the same color as the originating call.
- Coral on the primary success response or headline message — one, maybe two.
Anti-patterns
- Message arrow pointing upward (reverses time — never).
- Activation bars that never close.
- Labels sitting over another lifeline — shorten or shift y into a gap.
- Swimlane-style lanes instead of lifelines (different grammar).
Lifeline primitive
<line x1="CX" y1="TOP" x2="CX" y2="BOTTOM"
stroke="rgba(45,49,66,0.20)" stroke-width="1" stroke-dasharray="3,3"/>
Activation bar primitive
<rect x="CX-4" y="TOP" width="8" height="H"
fill="rgba(45,49,66,0.06)" stroke="#4f5d75" stroke-width="0.8"/>
