/*
 * Hand-written static CSS foundation for Phase A — NOT a Tailwind build.
 * BigRock has no Node/npm (confirmed in Phase 0), so this app cannot run a
 * Tailwind build step on the server; any future Tailwind output must be
 * compiled locally/in CI and uploaded as a static file, same as this one.
 * Tokens below (colors, radii, spacing) are matched by eye against the
 * current Next.js app's Tailwind classes (bg #F4F6F9 body, Inter font,
 * blue-700 primary, slate-200 borders, rounded-xl/2xl cards) — not a
 * pixel-perfect port, just enough for Phase A parity testing per the brief.

 * Fixed-layout operational tables (Frontend Fix Round 1).

 * opportunity/product string can force that column (and the whole table)
 * wider than intended, visually crowding or bleeding into neighboring
 * columns despite .cell-wrap's `max-width` (a soft hint auto-layout is
 * free to ignore once ANY cell's unbroken content demands more room).
 *
 * .data-table--fixed switches to `table-layout: fixed`, which makes each
 * column's width authoritative (taken from the .col-* class on that
 * column's <col> element below) and makes overflow WITHIN a cell always
 * stay within that cell's box — the standard, structural fix for this
 * class of layout bug, not a per-table patch. Combined with the existing
 * .table-scroll (already `overflow-x: auto`), a table whose declared
 * column widths sum wider than the viewport scrolls horizontally instead
 * of squeezing — the deliberate responsive strategy for these operational
 * tables (over a separate mobile card layout per table), since it reuses
 * a mechanism already in place and guarantees zero overlap at any width.

/*
 * Responsive breakpoints (Frontend Fix Round 1).
 *
 * Previously the only responsive rule in this file was the 900px
 * card-grid collapse above — the header and page padding had no
 * adaptation at all below desktop width. Operational tables use
 * controlled horizontal scrolling (.table-scroll, already in place) as
 * their responsive strategy rather than a separate mobile card layout per
 * table — .data-table--fixed's declared column widths give every table a
 * predictable min-width, so on a narrow viewport it scrolls cleanly
 * instead of squeezing or overlapping.
