/* Rishi Trading App — foundation stylesheet.
 *
 * Copied verbatim from the approved visual contract, design-2-sidebar-app.html
 * (the mockup is canonical; values are preserved exactly). This file holds the
 * SHARED design system only: tokens, reset, typography, and the reusable
 * component vocabulary — app shell, panels, tables, buttons, pills, forms —
 * plus accessibility utilities and the honest placeholder. Screen-specific
 * components arrive with the screens that need them in later tasks.
 *
 * INTERFACE SCALE — changed by Rishi on 25 Jul 2026. He used the built app,
 * said it "looks too big", found 80% browser zoom right, and chose to make
 * that the default at 100% zoom. The whole system is rem-based, so the scale
 * lives at the root and NOWHERE else: `html { font-size: 85% }` (106.25 x 0.8)
 * shrinks type AND every --space-* step together, exactly like 80% zoom.
 * Never re-tune individual font sizes to "fix" this; change the root instead.
 * This deliberately supersedes the earlier "17px base / nothing under 16px"
 * rule — Rishi was told the base lands near 13.6px and confirmed it anyway.
 *
 * Hard rules still in force: no light-grey text (every text colour is
 * --ink-soft or darker, all >= 4.5:1); green/red reserved for Rishi's money —
 * no hover, fill or decoration may borrow them; reduced-motion honoured.

     Today's stock rows are now tall blocks, so hovering flooded a big area
     with a pinkish wash and Rishi read it as a money state. Green/red are his
     money only, so hover now carries no hue at all: chroma is literally 0, so
     this rasterises to rgb(231,231,231) — red, green and blue identical.
     It is also a stronger signal than the tint it replaces: against the
     sidebar the old tint was 1.013:1 (a hue shift with almost no lightness
     change), this is 1.09:1; on Today's blocks 1.06:1 becomes 1.14:1; on a
