/**
 * SecurityHeaders — theme-hardened styles.
 *
 * Same defensive playbook we learned in the KloudScan clash:
 *   1. Every selector uses .securityheaders.securityheaders to double
 *      specificity (0,2,0) and beat most theme selectors.
 *   2. Aggressive reset on form controls (inputs, buttons, selects) neutralises
 *      inherited theme paint before our component styles apply.
 *   3. The container is its own white paint surface with its own typography
 *      so it stays legible on dark or opinionated themes.
 *   4. Targeted !important on paint properties defeats theme rules that
 *      also use !important.
