/* FILED design system.
   Four agents write into this page. Everything below is the shared vocabulary:
   use these tokens and these class names, do not invent a second palette.

   PALETTE
     --bg --bg-1 --bg-2 --bg-sunk   page, panel, raised/hover, chart plot ground
     --rule --rule-2                hairlines, the heavier one for panel edges
     --ink --ink-2 --ink-3          primary, secondary, smallest legible text
     --accent                       the single accent. Findings only: a company
                                    missing its promise, an active nav item, a
                                    number the argument turns on. Never decoration.
     --cool                         the counterpart state (beating the promise,
                                    EPA-measured data). Pairs with accent and
                                    stays apart from it under GIF compression.

   COVERAGE TIERS  (the honesty colours, identical in every section)
     --tier-measured      EPA GHGRP tonnage, filed under 40 CFR Part 98
     --tier-reported      voluntary self-report only, no mandatory tonnage
     --tier-unmeasurable  no mandatory tonnage at all
     --muted              == tier-unmeasurable. Use for any "we cannot measure
                          this" mark anywhere on the site. It is a declared
                          state, so it gets a colour, never a gap and never a 0.
     --muted-ink          text tone for that same category (the fill tone is too
                          dark to read as type)

   TYPE
     --font-sans body, --font-mono every figure without exception.
     --fs-fig 56px headline figures, --fs-h1 40, --fs-h2 26, --fs-h3 19,
     --fs-body 16, --fs-sm 15 (floor for prose), --fs-tick 14 (axis ticks only).

   SPACE   --s1 4 --s2 8 --s3 12 --s4 16 --s5 24 --s6 32 --s7 48 --s8 64

   LAYOUT  fixed left nav (--nav-w) + .main. One <section class="section"> per
           anchor, each opening with .sec-head. Content sits in .panel blocks.

   COMPONENTS  .panel .panel-head .panel-title .panel-n .stat .tbl .chip
               .legend .note .kv .bar-stack .card
   SVG         class the elements: .grid-line .axis-line .tick-label .axis-label
               .ref-line .pt .pt-label .tier-measured/.tier-reported/
               .tier-unmeasurable set fill from the tier tokens.

   RULE: every chart states its n in .panel-n, and every panel that hides a
   caveat in its JSON meta prints it in a .note underneath. */
