NOTATION — SHARED UI CONTROL FILE

Conclusion: control the interface here, then compile to assets/css/ui.css.
Reasoning, from general to specific (Minto):
  1. Settings define the design decisions.
  2. Foundations establish the shared defaults.
  3. Shell establishes the page geometry.
  4. Components implement each responsibility once.
  5. Responsive rules adapt those decisions by viewport.

MECE ownership: typography/reset → foundations; page positioning → shell;
navigation → navigation; expanding rows → accordions; prose/media → content;
tiles/paging → archive; legacy footer → optional footer; access helpers → accessibility.
A component owns both its geometry and appearance. Responsive overrides are
intentional exceptions, not a second competing definition.

HTML/copy lives in .hbs. Opening, filtering, pagination and the natural scroll
endpoint live in main.js. Sass is a build tool; the browser only loads CSS.
