Quiet resting cells in tables canvas

 | 2026-03-21 | P3.4 | Completed | Added a sticky context bar with reference-mode tabs, variant and severity selectors, roll-jump state, and active filter chips, then wired those controls into page state and canvas filtering. |
 | 2026-03-21 | P3.5 | Completed | Reworked the canvas with sticky headers, a sticky roll-band column, row and column emphasis driven by selection and roll-jump state, selected-cell treatment, and a comfortable/dense density toggle. |

 ### Lessons Learned
 
@@ -101,6 +102,7 @@ It is intentionally implementation-focused:
 - Rail keyboard behavior is easiest to maintain when it works from one deduplicated option order, even if the UI shows multiple sections. Keeping one internal option list avoids separate arrow-key state per section.
 - The context bar controls should own one shared view-state model before the canvas gets more visual treatment. Wiring the filters into the host page now avoids a second refactor when row, column, and cell emphasis land.
 - Canvas emphasis becomes maintainable once selection, roll-jump, and density are all fed through one explicit state model. That lets the grid respond to context without hiding selection logic inside CSS-only heuristics.
+- Resting-cell quietness should be enforced structurally, not only visually. Showing actions only for the selected cell prevents future CSS regressions from reintroducing button clutter across the whole grid.
