/* ── Light theme override ─────────────────────────────────────────────────
   Dark (Meridian) is the default and defined on bare :root above. Toggling
   light mode stamps data-theme="light" on <html> (see app.js: toggleTheme);
   this block redefines only the tokens that actually change — surfaces,
   text, divider, shadows, and (critically) the full neutral ramp — so every
   component class and inline var(--...) reference in the app repaints
   automatically with no per-element changes. Accent/chart/semantic hues are
   kept as-is: they're already tuned to read on both a near-black and a
   near-white ground.

   The neutral-100..900 ramp is used all over the app as secondary/muted TEXT
   (labels, sub-stats, footer captions) and was originally tuned one-directional
   for dark mode: neutral-200 (#dde4ec, near-white) reads fine as text on a
   near-black surface, but is nearly invisible as text on a near-white one.
   Flipped end-for-end here so every existing var(--color-neutral-N) reference
   still gets "a legible, appropriately-muted text color for this theme" —
   neutral-900 (darkest) takes neutral-100's dark-mode role and vice versa. */

     against — everything washed into one flat white. This pass gives the
