/*
 * Preloader — rising bubbles
 * ---------------------------------------------------------------------------
 * Same visual language as the Experience section's glass bubbles, but this
 * copy lives here in sections.css (not the deferred animations.css) so it's
 * guaranteed to be present the instant the preloader itself paints — the
 * preloader is the very first thing a visitor sees, so it can't be waiting
 * on anything.
 *
 * #preloader is a flex container, and per the Flexbox spec flex items paint
 * as if they were positioned with z-index:auto regardless of their actual
 * `position` value — so .preloader-decor (placed first in the DOM, in
 * index.html) naturally paints behind .loader-blob and the progress bar
 * without needing z-index gymnastics. The explicit z-index below is just
 * belt-and-suspenders so this doesn't silently break if someone reorders
 * the markup later.
 *
 * bubbleRise is defined once here (rather than duplicated) because it's
 * also used by the Experience section's bubbles in animations.css — CSS
 * keyframes are global, so a rule in one stylesheet can reference a
 * @keyframes block defined in another without any import machinery, as
 * long as both are eventually part of the page's CSSOM, which they always
 * are here (base/sections load unconditionally, animations.css always
 * follows once its preload swap fires).
 *
 * #preloader's own overflow:hidden (needed so rising bubbles don't cause
 * a stray scrollbar edge-case) lives with its main rule block in base.css,
 * not forked into a second file just because this comment is here.

/*
 * Floating Glyphs — refined
 * ---------------------------------------------------------------------------
 * Original bug: font-family referenced var(--font-mono), a token that was
 * never declared in variables.css, so every glyph silently rendered in the
 * inherited body font instead of monospace. Fixed below.
 *
 * Original animation: all 8 glyphs shared one `float` keyframe with identical
 * timing, so they all swung in perfect lockstep — reads as robotic, not
 * organic. Refactored into a single parameterized keyframe (`codeDrift`)
 * driven by per-element custom properties (--fx / --fy / --frot / --fdur /
 * --fdelay), with each glyph getting its own drift vector, duration, and a
 * NEGATIVE animation-delay. Negative delays make the animation act as if it
 * had already been running for that long — so on first paint, all 8 glyphs
 * are already mid-flight at different points in their cycle instead of all
 * starting from the same pose in sync. That one trick is what sells the
 * "ambient, alive" feel instead of "8 clones swinging together."

/* Tier 2 Modal (Fullscreen viewer)
 * ---------------------------------------------------------------------------
 * ROOT-CAUSE FIX for a real UX bug: scrolling a tall image used to scroll
 * the ENTIRE .fullscreen-viewer box, taking the "fixed" close/prev/next
 * buttons along with it — so at the bottom of a tall screenshot, those
 * controls were off-screen and you had to scroll all the way back up to
 * use them.
 *
 * Why this happened: `backdrop-filter` (like `filter`, `transform`, and
 * `perspective`) makes an element the CONTAINING BLOCK for any
 * `position:fixed` descendant, per spec. .fullscreen-viewer has
 * `backdrop-filter: blur(10px)`, so .fs-close/.fs-prev/.fs-next were never
 * actually fixed to the viewport — they were fixed relative to
 * .fullscreen-viewer's own box. That's invisible as long as that box never
 * moves/scrolls, which is exactly the fix below: .fullscreen-viewer no
 * longer scrolls at all (`overflow: hidden`), and scrolling is scoped
 * entirely to .fullscreen-content instead. The buttons' box now never
 * moves, so their fixed position holds correctly no matter how far the
 * image inside is scrolled.

/*
 * Decor-layer FOUC guard
 * ---------------------------------------------------------------------------
 * animations.css (Services blobs, Portfolio balls, Experience bubbles,
 * Social snake frame) is loaded non-render-blocking via preload+swap, which
 * means for a brief window after first paint it hasn't arrived yet. Without
 * this rule, the plain <div>/<svg> decor markup would flash as unstyled,
 * default-positioned elements before animations.css applies real positioning
 * and opacity. This single rule keeps them invisible until that stylesheet
 * loads and overrides it — zero flash, and it costs nothing on the critical
 * path since it's a single trivial selector.
 *
 * Deliberately only targets the OUTER .decor-layer element, not `.decor-layer *`.
 * opacity is not an inherited property, but it IS compositing: a parent at
 * opacity:0 renders its entire subtree invisible regardless of any opacity
 * a descendant sets on itself. Zeroing every descendant individually would
 * mean animations.css would need to re-override each one by name (fragile,
 * easy to miss one — e.g. an SVG <path> with no class of its own would stay
 * invisible forever). One rule on the parent is enough and can't drift.
