max-w-md (448px) under-sized the panel vs its real full-width tab placement and
never triggered the desktop two-column layout. Widen to max-w-3xl; note to
resize to ~390px for the mobile (single-column) check.

Addresses the static review + adds a dev-only visual harness:
1. Tape no longer overflows narrow mobile: each row stacks (label + read on one
line, cells below) under sm, keeping the single-line grid on desktop.
2. Date-only strings (earnings, price_date) are parsed as LOCAL calendar dates,
so a viewer west of UTC no longer sees the previous day.
3. Peer context is visible ("med X · Np") on every width and the percentile
strip carries a full aria-label — no longer hover-only / desktop-only.
4. Per-metric provenance + freshness surfaced (SEC filings · latest quarter,
filed date) replacing the removed panel-wide FMP label.
5. Same-day earnings render "today", not "in 0d".
Harness: frontend/harness.html + src/dev/harness.tsx (dev-only, served at
/harness.html by vite, not in the production build) render full /
partial-insufficient-peer / empty fixtures for desktop + ~390px review.
tsc -b passes.
