 - [x] Lucide icon sprite from `lucide-static` (dep added) → `views/partials/icons.ejs`; serve/inline only the icons used. → `src/icons.ts` (id→lucide map + `buildIconSprite`) generates a hidden `<symbol>` sprite of the 31 icons the mockups reference, paths sourced from pinned lucide-static; `icons.test.ts` guards provenance + only-used. Stale image rebuilt (lucide-static was missing). Wiring into the app shell is the next item.
 - [x] App-shell partial (sidebar + topbar + content slot). → `views/partials/shell.ejs`: full document wrapping `.app` → sidebar (brand + `nav` slot + theme/profile footer) · `.scrim` · `.content` (`.topbar` + `body` slot); reuses the mockup's classes (styled by `styles.css`), inlines the icon sprite. Slots `nav`/`actions`/`body` are HTML locals, `title`/`brand`/`user`/`breadcrumbs` text; defaults render standalone. `shell.test.ts` covers landmarks, slots, escaping, defaults. Not yet routed (that's "replace placeholder index").
 - [x] Nav-tree partial — recursive, header/leaf × clickable/static, counts, `aria-current`. → `views/partials/nav-tree.ejs`: data-driven, self-including. Node `{ label, href?, icon?, count?, current?, open?, children? }`; header (children → `.nav-disc` toggle + sibling `.nav-children`) vs leaf (spacer), clickable (`<a>`) vs static (`<span>`), orthogonal. Renders into the shell's `nav` slot. `nav-tree.test.ts` covers the full matrix + counts/icons/aria-current/escaping/empty.

+- [x] Filter-bar partial — GET form (search, segmented, selects, chips, daterange, applied pills). → `views/partials/filter-bar.ejs`: data-driven `<form method="get">` (server-side, zero-JS). `rows: Control[][]`, `type ∈ search|segmented|select|chips|daterange|spacer`, each reflecting current value (checked/selected); plus applied `pills` (+ remove links, Clear all) and Reset/Apply actions. Columns/“more filters” menus deferred to the menu/popover item. `filter-bar.test.ts` covers every type + value reflection + pills + defaults.
 - [ ] Data-table partial — sortable headers, row-select, badges, kebab row actions.
 - [ ] Pagination partial — rows-per-page + page numbers, query-param driven.
 - [ ] Form-field partials (input/label/hint/error) + auth-card partial.
