A heritage-mascot HVAC system: deep navy grounds, taxi-yellow uppercase CTAs, asymmetric opposite-corner radii, and the corner-bracket image treatment. Extracted whole from dashservice.com — every pattern transcribed, nothing invented.
#101f60 grounds with #fae80b uppercase Montserrat-Bold CTAs — the mascot-truck palette applied flat, red reserved for the mascot.
20px 0 20px 0 on cards, 50px 0 50px 0 on large mounts, with a blue-cast shadow. No symmetric rounding anywhere.
The .angles image treatment: mascot wedge PNG top-left, solid yellow border-triangle bottom-right.
"Since 1931", "Dashin' Good Technicians", "When you need it in a FLASH call DASH!" — the pitch is age plus speed.
