Summary

The speed cluster draws the coins as ADR 0105's pile, the coins take 3 from docs/mockups/coin-and-tyre-gauge-variations.html. The pile goes down the cluster's left and the gear plate moves right.

• Slots come from tuning.coinCap, not a hard-coded 10.
• coinCount, coinIcon and COIN_OCTAGON are retired along with their tests.
• palette.ts writes --coin and --coin-rim for the slots' gradient.
• This differs from the mockup on purpose: an empty slot keeps a held coin's height and draws its faint line inside, so the cluster holds still as the pile rises and falls.
• The style guide's Speed cluster entry now shows 0, 7 and 10 coins.
• Not included: a coin dropping onto the pile on pickup, as the issue says.

Evidence

• Before: the readout's text was x07 / 10, beside an octagon icon.
  After: instrument-panel.test.ts:

  drive(coins 7)  -> text "7", aria-label "7 of 10 coins"
  drive(coins 10) -> text "10"
  spin-out to 7   -> text "7"
  coinCap 6, 2 coins -> slots held [f f f f t t]
  

  Vitest passes 930 tests. race.spec.ts (5) and coins-of-eight.spec.ts (eight tabs) pass when run alone.
• Smoke test: the Instrument panel staged at 0, 7 and 10 coins. Its bounds stay at 22,543 to 353,698 at every count. With BOX, STOP and RAIN forced visible, all three plates sit at x 364 or more, clear of the cluster, without overlapping each other.

Screenshots:

0 coins	7 coins
10 coins	10 coins, BOX, STOP and RAIN forced visible

Merge Danger

Door: two-way

A revert restores the old readout. Nothing is persisted and nothing goes on the wire.

Blast Radius: HUD

The cluster grows a column wider and about 15 HUD units tall at the bottom-left. It could crowd the View in small windows during the eight-window feel check.
