Theme Name: Zen Tech Hub
Theme URI: https://zentechhub.com/
Author: Dhanvi Gupta
Description: Editorial theme for zentechhub.com, carrying the design of the original Astro site into WordPress — the same ink/paper/accent token scale, Inter and Newsreader. Pairs with the Sitecraft Blocks plugin, whose section blocks are retuned to this palette.
Version: 1.0.0
Requires at least: 6.0
Requires PHP: 7.4

/* Lifted verbatim from the live Astro build, token names and all, so the
   migration is invisible and anything copied between the two still matches. */
