Theme Name: Trustline
Theme URI: https://example.com/trustline
Author: Trustline Studio
Author URI: https://example.com
Description: Trust Ledger — a calm, audit-document design for cautious brand-review editorial content (regulated-vertical guides: licence checks, bonus terms, payment caveats, verification steps). Verdict panels read like certificate stamps, rating boxes read like ledger sheets, and a muted traffic-light signal system (verified / partial / unverified) runs through every callout. No page builder, no SEO plugin required — all SEO logic lives in the theme.

Design card
------------
Composition   : Single reading column with a right-hand sticky rail on pages
                that have enough headings for a TOC (breadcrumbs + TOC +
                "related in this section"); the front page (hub) keeps its
                own two-column hero. A dedicated "explore this section"
                block auto-lists sibling/child pages using native WP page
                hierarchy — no manual interlinking markup needed from the
                theme's side, since the imported content already carries
                its own hand-written editorial links.
Header        : Single clean layout — logo left, primary nav right, a thin
                "editorial guide, not an operator" disclaimer strip above it.
Palette       : Warm paper background, ink-navy text, one ledger-navy accent
                for links/brand, plus a muted three-state traffic-light
                signal system (verified / partial / unverified) used
                throughout verdict panels, rating boxes and scorecards.
Typography    : A serif (Source Serif 4) for headlines — evokes a printed
                report rather than a marketing page — IBM Plex Sans for body
                copy, IBM Plex Mono for status stamps, ledger labels and
                numeric data.
Cards         : 1px hairline border, small 10px radius (an "official
                document" corner, not zero, not fully rounded), no shadow at
                rest, a soft lift shadow on hover — restrained throughout.
Motif         : Certificate-style dashed inner rule on the verdict panel,
                monospace bracket-stamp labels ([VERIFIED] / [PARTIAL] /
                [UNVERIFIED]), ledger-sheet row dividers on rating boxes and
                tables.

IMPORTANT — this theme's compatibility architecture is different from its
sibling themes (Matchline / Oddsline, built for a different content family).
------------------------------------------------------------------------------
Those themes import content that ships its own per-page <style> block
printed after the theme's stylesheet, so their CSS had to avoid ever tying
in specificity with that incoming content stylesheet.

This content family (brand/regulated-vertical review guides) ships NO
per-page stylesheet and NO inline styles at all — every page in the family
uses one FIXED, shared set of semantic class names (hero-grid, verdict-panel,
rating-box, table-wrap, split-section, cards/three/four, info-box,
check-list, numbered-list, route-map, eyebrow, lead, hero-actions, hero-card,
plus native <details>/<summary> for FAQs). Those class names are a stable
content contract for this whole family, not one-off per-import styling, so
this theme owns them directly and styles them as first-class components —
no specificity-avoidance strategy needed here, no !important anywhere.
Only this theme's OWN new chrome (shell, nav, breadcrumbs, TOC rail,
pagination, related block, footer) is prefixed "tsl-" — content classes are
used exactly as the content contract defines them, unprefixed.
