/* Panda Exteriors — "Our Project Gallery" ("ppg", see README.md in this folder). Every rule
   is scoped to .ppg / .ppg-lightbox, so nothing else on the site is affected.

   Category tabs, then a row of same-size photos that scrolls sideways (snapping to whole
   photos) with the arrows and dots centred below it. project-gallery.js adds .is-ready and
   runs the tabs, arrows, dots, mouse dragging and the photo viewer; without it, every
   photo is in the row. */
