/* ==========================================================================
   XpressGrow — themes
   --------------------------------------------------------------------------
   Each theme is a complete swap of the colour tokens declared in site.css.
   Nothing else changes: no layout, no type, no spacing. If a theme looks wrong
   somewhere, the cause is a hard-coded colour in a component — fix it there by
   adding a token, never by patching the theme.

   Midnight is the default and lives in site.css :root, so the site works with
   this file absent.

   LIGHT THEMES: two things must invert or they fail silently —
     · --line/--fill are white-alpha on dark and MUST become black-alpha, or
       every hairline and panel wash vanishes on a pale canvas.
     · --shadow is near-black on dark; at 0.85 under a white card it reads as
       a dirty smudge rather than elevation. Light themes use a much softer,
       slightly blue-black shadow.
