/* ===========================================================================
   tools.css v2 - "Through the viewfinder, disciplined"
   The shared kit for the thirteen free photographer tools at /tools.
   ---------------------------------------------------------------------------
   Every tool is one camera body: a slab (.vf-camera), a window (.vf-finder or
   .vf-display) with HUD corner blocks, a caption line, a scrub bar, an info
   bar, a deck of body controls, marginalia, a menu page, the essay, one
   shutter CTA. Document-shaped tools use a paper .sheet instead of a window.

   Scope: everything new lives under .vf (the page wrapper every tool adds
   around .tool-wrap), under .sheet, or is prefixed vf-/tc-/tr-. Nothing here
   reaches .seo-* or the marketing pages. Typography is Inter and JetBrains
   Mono only, through --font-sans / --font-mono from style.css. No @import.
