/* ─────────────────────────────────────────────────────────────────────────
   Light theme — white / black / green, Poppins.
   Overrides the Nocturne token layer. Because every page styles against
   var(--*), remapping the tokens here re-themes the whole site.
   The ramps are INVERTED relative to the dark theme: steps 100–400 are the
   dark, readable greens (text, icons, numbers) and 700–900 are the pale
   tints (glows, fills) — so existing usage keeps its meaning on white.
   Remove this <link> from a page to return it to the dark Nocturne theme.
