/* SotaTek theme — activated by SOTADOCS_THEME=sotatek.
 *
 * Source of truth is sotatek.com: the brand tokens declared in the site's own
 * stylesheet (--c-main-6 #036ae5 primary, --c-main-1 #121a45 / --c-main-3
 * #01105b navy, --c-main-7 #101624 text, --c-main-9 #565c69 body grey,
 * --c-main-10 #71a2ff, --c-main-2 #2fabdd cyan, --c-bg-1 #f6f8fc,
 * --c-orange #fcb415, #e5e7ef borders), the Be Vietnam Pro typeface the site
 * loads from Google Fonts (self-hosted below so the app stays offline, OFL 1.1
 * — see fonts/OFL.txt) and the site's white header carrying only the mark.
 *
 * The site's look is not "grey admin dashboard with white cards". It is:
 *   - a WHITE page,
 *   - big rounded light-blue gradient panels (its hero/product bands) floating
 *     on that white, with a hairline edge,
 *   - very large, heavy, tightly tracked headings; band headings uppercase
 *     with a blue gradient running through the letters,
 *   - tiny uppercase blue micro-labels above headings ("01-PRODUCT",
 *     "WHITEPAPER", "OUR SERVICES"),
 *   - hairline dividers and tab strips instead of boxed frames,
 *   - brand blue used as an accent — icon chips, labels, links, compact CTAs —
 *     never as large filled areas,
 *   - generous whitespace and comfortable 16-20px card radii.
 *
 * That is what the rules below implement on top of the shared templates. The
 * default theme stays untouched; everything is scoped to this stylesheet, which
 * base.html loads last. Rules that must survive the base sheet's own media
 * queries are repeated at the bottom on purpose: at equal specificity source
 * order decides, and this sheet is last. A couple of !important flags are used
 * to beat inline styles written into the templates (margins in the dashboard
 * header row); each one is called out below. */
