  SITE COLOR GUIDE
  Change the variables below to update the whole site's palette.
  --bg: main page background.
  --ink: primary text, nav links, footer text.
  --muted: hover color and active nav link color.
  --line: thin borders and dark placeholder panels.
  --overlay: lightbox background color.

  Quick edit recipe:
  1. Pick a new background color and put it in --bg.
  2. Pick a readable text color and put it in --ink.
  3. Pick a softer version of the text color and put it in --muted.
  4. Pick a subtle border color and put it in --line.
  5. Match --overlay to --bg, but use rgba() with about 0.92-0.96 opacity.

  Also search this file for "SUPPORT COLOR" when changing palettes.
  Those few values control body-copy text and placeholder panel colors that
  should complement the main variables.

  Example light palette:
  --bg: #f7f1e6;
  --ink: #2a241d;
  --muted: #7b705f;
  --line: #dfd3bf;
  --overlay: rgba(247, 241, 230, 0.94);
*/
:root {
  /* Cream theme. Adjust these five values to recolor the whole site. */
  --bg: #f7f1e6;
  --ink: #2a241d;
  --muted: #7b705f;
  --line: #dfd3bf;
  --overlay: rgba(247, 241, 230, 0.94);
  /* Shared side padding for the top nav and Overview photos so they line up. */
  --overview-side-padding: clamp(97px, 16.2vw, 297px);
