/* WP-D1 - templates/portfolio/projects.html only.
 *
 * Every selector here is scoped under .pp-page and every class is prefixed
 * pp- deliberately. The `projects` Page row's already-assigned CSSStyle
 * rows (loaded globally via templates/base.html whenever `page` is in
 * context - see docs/MOCKUP_DECISIONS.md Annex A.1, "page also drives
 * per-page CSS... simply not passing page... would strip the projects
 * page's assigned styles") define their own unprefixed .category-filter,
 * .project-card and .tech-badge rules for the legacy blob layout. Reusing
 * those class names here would silently pull in that unrelated styling
 * (or fight it on cascade order) - this file exists precisely so the new
 * mockup-matching layout does not depend on, or collide with, that legacy
 * CSS. Nothing here is a redesign of the legacy classes; that is out of
 * WP-D1's scope. Palette, layout numbers and selectors are carried over
 * from docs/mockup_projects_and_workfeed.html's own <style> block
 * (the "functional" rules only - the mockup's own documentation chrome
 * such as .viewport/.tag/.wire/.ruling is not reproduced here).
