UX-27: Soften Home primary action card color

[Chris0Jeky]

Summary

• Replace full ember-red (--td-color-ember-glow) background on .td-home-action--primary with subtle --td-color-ember-dim (10% opacity) background
• Add border-left: 3px solid var(--td-color-ember) accent for visual hierarchy without alarm
• Soften hover state: lighter rgba overlay instead of full ember + red glow box-shadow
• Reserve full-red backgrounds for actual urgency (overdue, blocked items)

Closes #627

Test plan

• Visual check: Home view "Next Step" card should appear as a subtle ember-tinted card, not alarming red
• Hover state should slightly darken the ember tint without a red glow
• Light mode: verify ember-dim token renders correctly (uses different opacity)
• No regressions on secondary action cards

Adversarial Self-Review

Diff reviewed: 1 file changed, 5 insertions, 4 deletions. CSS-only change in HomeView.vue.

Findings

1. Hardcoded hover rgba value (minor): The hover state uses rgba(255, 77, 77, 0.18) instead of a design token. There is no existing token at ~18% opacity in design-tokens.css — the closest is --td-color-ember-dim at 10%. This is acceptable for now but could be extracted to a token if the pattern recurs.

2. border-left vs base border shorthand: The base .td-home-action sets border: 0.5px solid transparent on all sides. The primary modifier overrides only border-left: 3px solid. This works correctly — CSS specificity means the left border gets the 3px ember, other sides keep 0.5px transparent. The 3px left border adds ~2.5px extra width which is negligible in a flex layout. No layout shift concern.

3. Light mode token behavior: --td-color-ember-dim has a separate light-mode definition using rgb(var(--_td-light-accent-rgb) / 0.07) — this will render even subtler in light mode, which is the correct direction.

4. Transition coverage: The base class transitions background, border-color, and box-shadow — the border-left change is static (not on hover), so the transition still covers the hover background change. The box-shadow: none on hover will transition smoothly from the base transparent border.

5. Acceptance criteria check:

   • Background changed from full ember to ember-dim
   • Color changed from inverse to primary text
   • border-left accent added
   • Hover state softened (no red glow)
   • Full-red reserved for urgency only

Verdict

No bugs or issues found. Change is minimal, focused, and matches the issue spec exactly.

Code Review

This pull request updates the styling for primary home actions in HomeView.vue, including changes to background colors, text colors, and the addition of a left border. Feedback was provided regarding a hardcoded RGBA value in the hover state, suggesting the use of a design token with color-mix to ensure theme consistency.

[gemini-code-assist]

The hover background uses a hardcoded RGBA value (rgba(255, 77, 77, 0.18)). This bypasses the design token system and will not adapt correctly to the Light Theme, where the ember accent color is different (defined as #d93636 in design-tokens.css). Use color-mix with the --td-color-ember token to ensure theme consistency and maintainability.

  background: color-mix(in srgb, var(--td-color-ember) 18%, transparent);
