## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Stylize journalism 'TK'/'tk' to-come placeholders so they pop as fill-in reminders. Decided: whole-word match (TK/tk/TKTK repeats), case-insensitive, prose only (skip code files, code spans, URLs, frontmatter, wikilink/link targets - same exclusions as spellcheck). Render as a filled 'badge' chip: padded ' TK ', bold, loud fg/bg pair. New theme token TK added to all 3 palettes (loud accent: magenta-ish dark, matching light/charm). Implement as a prose post-pass in buildVisual (like spellPass/grammarPass) splitting prose spans and re-emitting TK tokens with the badge style. TDD.
