/*
 * ui.css — minimal replacement for bootstrap.min.css.
 *
 * Covers only the mechanics this site actually uses (verified by grepping
 * every .html/.php page for data-bs-* attributes and Bootstrap classes):
 * navbar/collapse, modal, carousel, nav-pills/tab-pane, the small grid
 * subset (row/col-12/col-md-6/col-md-12/col-lg-4/g-3/g-4), form controls,
 * and a handful of utility classes that aren't valid Tailwind utilities
 * (d-flex, fw-bold, small, lead, rounded-circle, justify-content-*,
 * align-items-*). Visual design (color, spacing, typography) is Tailwind's
 * job — this file only makes things position/show/hide/animate correctly.
 */

/* ===== Heading defaults =====
 * Tailwind's Preflight reset sets h1-h6 to `font-size: inherit`, so any
 * heading across the site that doesn't carry an explicit Tailwind text-size
 * utility (many don't — they rely on the page's own custom classes like
 * .section-title, which only set color/weight, not size) silently collapsed
 * to the body's 16px instead of looking like a heading. Restoring Bootstrap's
 * original Reboot sizes here fixes every one of them at once; a real
 * text-3xl/text-xl/etc. class on a given heading still wins (a class
 * selector always beats a bare element selector), so already-upgraded
 * headings are unaffected. */

/* Same story as headings: Tailwind's Preflight strips list-style/padding from
 * every <ul>/<ol> (`list-style: none; margin: 0; padding: 0;`), so any plain
 * content list that expected a browser-default bullet/number (recipe
 * ingredients, product uses, job requirements, etc.) silently lost it.
 * Nav-purpose lists (.navbar-nav, .nav, problem/cause/location lists with
 * their own icon-based bullets) already set list-style:none themselves via a
 * class, which — being a class selector — still wins over this element
 * default, so they're unaffected. */
