Bars communicated "events," not "where the account level sits." A sparse-deposit account painted three thin bars at the bottom and looked dead. An account with a single big deposit dominated every other row's scale. Swap to the same visual language as the projection chart on goals#show — filled area below a stroked line — but one chart per linked account, rendering that account's actual balance trajectory over the last 90 days. Mechanics: - New `trajectory_map` on the component pulls every `balances` row for every linked account in one query (`Balance.where(account_id: account_ids, date: 90d..today)`). Result is grouped per account and resampled to 24 points by a single-pass forward walk that carry-forwards the most-recent balance at-or-before each anchor date. O(rows + samples), not O(rows × samples). - Per-row Y-scale: baseline 0 (when the account has ever held a positive balance), ceiling = max balance × 1.05. The chart reads as "how full was this account over time" rather than "how dramatic is the shape." Flat-at-$5k accounts paint near the top; growing $200 → $500 accounts climb from 40% to top. - Filled area at `opacity: 0.18` in the account color + stroked line at full opacity on top — same treatment as the projection chart's saved series. - Grid track for the chart column widened from `minmax(60px, 1fr)` to `minmax(80px, 1fr)` so the curve has enough horizontal room to read. Removed `shared_spark_max` + `sparkline_map` + the bucketed inflow sparkline machinery. Per-row scale is correct here — magnitude already lives in the weight pill on the left and the "$X last 30d" column on the right; the chart's job is shape.
