- why-panel tab swap is a proper opacity+transform crossfade (display:grid
stack area) instead of display:none jump; 650/800ms ease-out.
- tab progress indicator animates linearly (timer, not eased).
- Panel 01: dropped redundant "Every command reads this…" footer; moved the
commands meta into the visual as a right-side sidebar aside PRODUCT.md.
- Panel 02: "Browse the full catalog →" moved under the Gallery of Shame;
pattern category tabs are now always a single-row horizontal scroll with
JS-tracked edge-fade mask and chevron affordances; click centers the
selected tab inside the strip (never scrolls the page).
- Panel 04: "register" → "mode" in body, labels, meta for plain-language.
- Panel 05: removed redundant "Works in Claude Code…" meta.
- Panel 06: removed "Spec-compliant. Interoperable. Not a proprietary
sidecar." meta.
- .language-content grid gap reduced from --spacing-lg to --spacing-sm so
the commands palette sits closer to the section lead.
