/* ============================================================================
   ClaudeLight site chrome — the header, app bar and footer on EVERY page
   (marketing pages, PIF, AMM, Expense). Markup: shared/site-chrome/chrome.php.

   Everything is namespaced .cl-* so it cannot collide with page or app CSS, and
   colours are variables that FALL BACK to the site palette: pages that define
   --ink / --paper / --sage … (index, dark, quote, pif, amm, PIF app) restyle the
   chrome with their theme automatically; apps with other token names (AMM,
   Expense) get the exact site look from the fallbacks.

/* ============================================================================
   PRODUCT SHARE — the sticky Share tab and its dialog, on every page.

   Shares a PRODUCT (the ClaudeLight site, PIF or AMM) and nothing else: never a
   calculation, a history row, or anything belonging to the signed-in user. The
   wording is each product page's reviewed og:title / og:description, so what a
   visitor sends matches what the link unfurls to.

   It lives in this file, not its own, because every surface already loads this
   stylesheet — the marketing pages and PIF link it directly; AMM, Expense and
   site/profile.php get it from cl_head_assets() — so "on every page" is true by
   construction rather than by remembering to add a <link> to each new page.

   The tab sits on the LEFT edge, mirroring the product rail on the right
   (assets/product-access.css), so the two never collide on the marketing pages
   that carry both. It replaces that rail's old bare-mailto .qa-share tab, which
   did nothing at all in a browser with no mail handler registered.

   Behaviour: assets/site-chrome.js.
