 * iCamBody Screw Finder - front-end styles.

 * Ported verbatim (design-wise) from icambody-screw-finder-simplified.html.
 * Every selector is prefixed with `.isf-` so the plugin does not collide
 * with theme styles (generic names like `.container`, `.hero`, `.card`,
 * `.section`, `.field`, `.set` would otherwise inherit theme rules).
 * Site chrome (utility bar, masthead, footer) lives in the host theme and
 * is intentionally NOT shipped by the plugin.

/*
 * Theme-override block.
 *
 * Goal: make our buttons immune to host-theme button styling without
 * accidentally beating our own class rules above. We boost specificity by
 * scoping to the parent containers (.isf-plate-actions, .isf-cards) so the
 * effective selector is two classes deep, which wins against any single-
 * class theme rule AND against tag-selector resets (e.g. `.entry-content
 * button { ... }`). Color values are explicit (not `revert`) so we don't
 * inherit user-agent defaults.
