   ui.css — shared primitives (design system v1, "quiet ledger")

   The catalogue with markup snippets is docs/specs/design-system.md. Tokens
   live in styles.css :root; this file has no :root and no colour literal of
   its own — everything is var(). tests/test_design_system_invariants.py
   holds it to that, and to these rules, so the cascade probe stays clean:

   - Every selector starts with `.pds-`; the only descendants are structural
     children (th, td, tbody tr, legend, svg, i). No IDs, no bare element
     selectors, no `!important`, no numeric z-index.
   - State is `aria-pressed` / `aria-selected` / `aria-current` / `aria-sort`
     / `:disabled`, never a bare `.active` / `.up` / `.down` — pages already
     own those names with other meanings.
   - Inherited properties (colour, font-size, weight, family, tracking,
     white-space) are declared on the container, never on a leaf like `td`, so a page's
     single-class colour (`.pds-pos` on a cell) wins at (0,1,0) with no
     compound selector. docs/specs/fixes/css-cascade-sweep-triage.md.
   - Polarity, never direction: `--pos` / `--neg` say good / bad. Whether "up"
     is good is the page's call (Remakes: no; Check-In: yes) and it maps in
     the template.

   Loaded by base.html, base_scan.html and login.html right after styles.css
   and before any page sheet, so an equal-specificity page rule still wins by
   source order while a page is mid-migration.
