One accent: #A6462F, and accentText becomes an alias

[maximsan]

The 3 Sep design drop (05ac53d) darkens the accent so it passes AA as text at 11px, and retires the two-colour rule:

• --accent: #A6462F (Cupping; was #B8533A) — the design's comment: "One accent colour, no second rule to remember." Dark Roast keeps #E07A4F.
• --accent-text: var(--accent) — "Deprecated alias, kept so the shipped mobile token set still resolves. New work uses --accent directly."

The app ships the old pair: MoodColors.accent is #B8533A and accentText is #783C2C in Cupping, with eleven label-step call sites on accentText (shipped by #359 / PR #419 — this drop reverses that ruling).

Acceptance

• Cupping accent is #A6462F; Dark Roast unchanged
• accentText equals accent in both moods (the alias kept, matching the design), stated in one line in the PR
• No screen still renders #B8533A
