/* ── Site Intelligence tab ────────────────────────────────────────────────
 *
 * Styling for the super-only analytics tab rendered by js/site-intel.js.
 *
 * BOTH-THEMES RULE (learned the hard way on the upload-gate closed card):
 * this file contains ZERO hex literals and ZERO rgb() literals. Every colour is
 * a theme token or a color-mix of one, so light and dark are correct by
 * construction rather than by a second set of overrides.
 *
 * `--card-bg` is a solid colour in both themes and safe to color-mix.
 * `--bg-main` is a GRADIENT in the light theme and must NEVER be passed to
 * color-mix — it silently produces an invalid colour and the element renders
 * transparent. See css/theme-tokens.css.
 *
 * Also: no `content:` string in this file carries a non-ASCII character. A
 * CSS content string is the one place an encoding slip becomes visible mojibake
 * on the page; every glyph the tab draws is an inline SVG built in JS.

/* ── Header ───────────────────────────────────────────────────────────── */

/* The header is a RAISED PANEL, not bare text on the page background. It is the
 * one band that stays put while the h1, the subtitle and every panel below it
 * change with the active sub-tab, so it needs to read as a fixed frame rather
 * than as the first paragraph of whatever tab happens to be open.
 *
 * The tint is mixed off `--primary`, not off a fixed grey: in the light theme
 * `--card-bg` is white and the page behind it is a warm beige gradient, so a
 * plain white panel would sink INTO the page rather than lift off it. Mixing a
 * little primary in gives the band its own hue in both themes, which is the
 * thing that actually makes it legible as a header. `--card-bg` is solid in both
 * themes and safe to mix; `--bg-main` is a gradient in light and must not be
 * mixed (see the file header). */

/* ── Charts (hand-rolled SVG) ─────────────────────────────────────────────
 *
 * No chart library is loaded on this surface, so every plot is SVG built in JS.
 * The one rule that matters: the JS emits CLASSES ONLY, never an inline colour,
 * so a chart is themed by this file exactly like the rest of the tab. Fills use
 * `fill`/`stroke` here rather than `color`, because an SVG shape ignores
 * `color` unless the JS asked for `currentColor`.
 *
 * `preserveAspectRatio="none"` on the viewBox lets a chart stretch to whatever
 * column width the 12-column grid gave it; the height is pinned below so the
 * stretch never distorts the type (text is drawn at a fixed viewBox size and
 * scaled uniformly by the browser). */
