  Inference Exchange — converted stylesheet (task 004).

  Source: `design/Inference Exchange.dc.html` + `design/styles.css`, per `docs/specs/design_spec.md`.
  The accent ramp below is the PAGE's own override (purple, #7c11f5) — not the shared system's
  default (red). See design_spec.md §2.

  ────────────────────────────────────────────────────────────────────────────────────────────
  DOM CONTRACT HOOKS — stable classes/ids tasks 005 (desk.js) and 006 (form.js) bind to.
  Neither task may edit index.html, so every hook they need is listed here.
  ────────────────────────────────────────────────────────────────────────────────────────────
  Trade desk (task 005):
    .js-model-tabs          — container of the four model tabs
    .js-model-tab           — each of the four model-tab buttons
    .js-ladder-bid-column   — the bid column (holds six .js-ladder-bid-row rows)
    .js-ladder-ask-column   — the ask column (holds six .js-ladder-ask-row rows)
    [data-testid="ladder-bid-row"] / [data-testid="ladder-ask-row"] — one per ladder row
    [data-testid="ladder-mid"] / [data-testid="ladder-spread"] / [data-testid="ladder-open-interest"]
    .js-ladder-summary      — the Mid / Spread / Open interest strip
    .js-tape-header         — the trade-tape panel's header row (title + Matching + stop control)
    .js-tape-list           — the trade-tape row list
    [data-testid="tape-row"] — each trade-tape row
    .js-desk-stop           — the stop control button ("Pause" / "Resume")
    .js-bucket-tabs         — container of the two bucket tabs
    .js-bucket-tab          — each of the two bucket-tab buttons
    .js-bucket-caption      — the note line beneath the bucket tabs (bucket note + sort note)
    .js-contracts-thead     — the contracts table <thead>
    .js-contracts-tbody     — the contracts table <tbody>
    .js-sort-btn            — each column's sort control (`data-sort-key` names the field)

  Waitlist form (task 006):
    .js-hero-cta            — both hero CTAs ("Buy tokens" / "Sell tokens"), `data-side` names the side
    .js-waitlist-form       — the <form> element
    .js-success-panel       — the success panel (sibling of the form; mutually exclusive at runtime)
    .js-side-option         — each of the two side radio wrappers
    .js-side-radio          — each of the two `role=radio` inputs (shared `name`)
    .js-contract-block      — the block revealed once a side is chosen
    .js-contract-heading    — swaps text between "The contract you need" / "…you hold"
    .js-latency-label       — swaps text between "Latency requirement" (buy) / "Latency" (sell)
    .js-model-select        — the Model <select>
    .js-submit-btn          — the submit control
    .js-submit-status       — the in-flight / failure message slot (empty until triggered)
    .js-field-error         — each field's inline error slot (`id` referenced by that field's
                              `aria-describedby`; empty text, reserved space, until triggered)
