/* BunnyQuery product section: the hero of web-bunnyquery's landing page
   (src/views/landing.vue, components/bunnyLoader.vue), ported to plain CSS.
   Every rule is scoped under .p-bunnyquery; the --bq-* tokens are the light
   theme of src/assets/less/bq-tokens.less, defined on the section itself.
   Keyframes are prefixed pbq-. Sizes are in px (1rem = 16px in the original)
   so the host page's root font size does not rescale the section.
