/* ==========================================================================
   T.M. Air Conditioning — company website (Summit demo deliverable, noindex)
   Clone of Summit's AC-benchmark engineering (longlife-ac), restructured as a
   multi-section evergreen company site. Brand skin sampled from TM's GENUINE
   logo (assets-src/tm_airconditioning_logo.jpg): deep navy ground #04122F,
   AC-blue snowflake #4BA4F4, light swirl #84C4F2, silver/white type.
   AA decisions (computed 2026-07-17):
     CTA fill  #1B72C2 (white text 4.96:1 — brand blue #2E8FE0 was 3.43:1, too
     low, so the CTA is the brand blue DEEPENED one step; hover #155EA6,
     active #0F5496).
     Text-role blue on white: #1868B3 (5.72:1).
     Bright accent on navy: #4BA4F4 (6.72:1 on #0A1730).
   No reviews/stars/ratings anywhere (TM has none — honesty ruling).
