   Liquid Glass — core component library                    v1 2026-07-01
   ═══════════════════════════════════════════════════════════════════
   THE DEFAULT LOOK. One place for the reusable glass components so any
   page can pick them up with a class — no per-page CSS.

   How the system layers (all already live):
     1. Hero background  — objects/background/heroes/settings.json
        ("sitewide": true → PageWrap::pagewrapnavbarbs sets --hero-bg-url
        on every wrapped page, rotating hourly).
     2. site-background.css — frosts #pw-content and EVERY .card inside
        it automatically; tunable via --glass-* vars; per-page opt-out
        via webqueryini.glassstyle or $GLOBALS['_glassstyle']
        ('none' = transparent container + frosted cards).
     3. THIS FILE — the component classes: headers, chips, pills,
        buttons, tiles, dashboard cards. Loaded site-wide by PageWrap
        beside site-background.css.

   To make a page feel Liquid Glass: stop painting opaque slabs
   (bg-dark blocks, solid border-* cards) and use these classes.
   agent-darkmode.css still carries older scoped copies of glass-btn/
   glass-pill for the agent homepage; new work should use these.
